00:00:27,120 --> 00:00:34,440
Speaker 1: Fromhowstuffworks dot com.

8
00:00:34,600 --> 00:00:37,200
Speaker 2: Hey, and welcome to the podcast. I'm Josh Clarr. There's

9
00:00:37,320 --> 00:00:39,879
Speaker 2: Charles W Chuck Bryant.

10
00:00:40,159 --> 00:00:43,840
Speaker 1: That's me, same as ever, scratching the old back.

11
00:00:44,040 --> 00:00:45,720
Speaker 2: Yeah, I just got a little itch there.

12
00:00:45,840 --> 00:00:47,840
Speaker 1: You ever use one of those little dealies, the little

13
00:00:47,920 --> 00:00:49,920
Speaker 1: creepy hand, the little monkey pap on the end of

14
00:00:49,920 --> 00:00:51,040
Speaker 1: the stick I have.

15
00:00:51,080 --> 00:00:55,560
Speaker 2: Before, Yeah, I don't like to do that. It hurts

16
00:00:55,840 --> 00:00:57,800
Speaker 2: do Yeah, I guess you could call it that some

17
00:00:57,920 --> 00:00:58,920
Speaker 2: painful sensation.

18
00:00:59,560 --> 00:01:02,640
Speaker 1: I get up gives the wall sometimes and do the

19
00:01:02,640 --> 00:01:03,360
Speaker 1: blue the bear.

20
00:01:03,560 --> 00:01:07,000
Speaker 2: That'll do sometimes too. But it's weird, like I only

21
00:01:07,040 --> 00:01:09,759
Speaker 2: have backages in about the same place, and that would

22
00:01:09,760 --> 00:01:14,080
Speaker 2: be on my left shoulder blade on the western side

23
00:01:14,120 --> 00:01:16,080
Speaker 2: of it, depending on which direction I'm facing.

24
00:01:17,040 --> 00:01:19,600
Speaker 1: Curiously, this is going to be the most interesting part of.

25
00:01:19,600 --> 00:01:23,280
Speaker 2: This show that is not a true Chuck Man, so Chuck. Yes,

26
00:01:23,600 --> 00:01:24,920
Speaker 2: this is going to be a great one.

27
00:01:25,040 --> 00:01:25,360
Speaker 1: Okay.

28
00:01:25,400 --> 00:01:26,640
Speaker 2: I have a feeling this is gonna be one of

29
00:01:26,640 --> 00:01:28,480
Speaker 2: those ones where it's like, wow, that turned out to

30
00:01:28,520 --> 00:01:31,040
Speaker 2: be really good. It's physics heavy out the y.

31
00:01:31,319 --> 00:01:32,280
Speaker 1: Yeah, everyone loves that.

32
00:01:32,480 --> 00:01:35,039
Speaker 2: But the fact is, when we finish this, you're gonna

33
00:01:35,080 --> 00:01:38,960
Speaker 2: know how yoyo works. This is probably the most truly titled,

34
00:01:39,680 --> 00:01:44,560
Speaker 2: truest titled episode. Well we've ever done, you think, yep?

35
00:01:46,040 --> 00:01:46,479
Speaker 1: I don't know.

36
00:01:46,560 --> 00:01:47,680
Speaker 2: All right, Well we'll find out.

37
00:01:47,800 --> 00:01:50,480
Speaker 1: I think it should be called Physics through the Eye

38
00:01:50,520 --> 00:01:51,080
Speaker 1: of a Yo yo.

39
00:01:51,520 --> 00:01:55,160
Speaker 2: So listen, have you ever seen the movie Harlem Knights

40
00:01:57,040 --> 00:01:59,840
Speaker 2: Parts dude? That is go back and watch it again,

41
00:02:00,400 --> 00:02:02,400
Speaker 2: the whole thing. Oh, you're crazy. It's one of the

42
00:02:02,440 --> 00:02:06,559
Speaker 2: best movies ever. Eddie Murphy, Red Fox, Richard Pryor, great

43
00:02:06,600 --> 00:02:08,760
Speaker 2: cast and like everybody else in it too. I think

44
00:02:08,800 --> 00:02:09,799
Speaker 2: Bernie Max in there.

45
00:02:09,880 --> 00:02:11,280
Speaker 1: Awesome cast, terrible script.

46
00:02:11,400 --> 00:02:13,000
Speaker 2: I don't think the script is terrible. I thought it

47
00:02:13,000 --> 00:02:16,680
Speaker 2: was great. There's one thing about that movie that bugged

48
00:02:16,720 --> 00:02:19,680
Speaker 2: me to know it it's set in like the twenties, right, Yeah,

49
00:02:20,360 --> 00:02:23,200
Speaker 2: and Throughout the movie, Eddie Murphy uses the word yo.

50
00:02:24,200 --> 00:02:27,320
Speaker 2: Yo is obviously a modern term, and it just sticks

51
00:02:27,320 --> 00:02:29,080
Speaker 2: out like a sore thumb every time he does. It

52
00:02:29,120 --> 00:02:31,400
Speaker 2: drives me crazy, Like it drives me crazy that he

53
00:02:31,440 --> 00:02:33,720
Speaker 2: did it drives me crazy that the director wasn't like,

54
00:02:33,880 --> 00:02:36,880
Speaker 2: you can't say yo. This is like nineteen twenties New York.

55
00:02:36,960 --> 00:02:37,799
Speaker 2: Yo wasn't around.

56
00:02:37,800 --> 00:02:40,359
Speaker 1: I don't know that they were going for historical accuracy

57
00:02:40,400 --> 00:02:40,840
Speaker 1: in that one.

58
00:02:40,960 --> 00:02:45,760
Speaker 2: They were wearing spats. Yeah, so Jerry like that one.

59
00:02:46,000 --> 00:02:48,280
Speaker 2: So I went back to the little digging Chuck and

60
00:02:48,320 --> 00:02:50,800
Speaker 2: it turns out that yo was in fact around in

61
00:02:50,840 --> 00:02:53,840
Speaker 2: the nineteen twenties, but Eddie Murphy was still wrong for

62
00:02:53,960 --> 00:02:57,680
Speaker 2: using it in that capacity. Okay, okay. So yo goes

63
00:02:57,720 --> 00:03:00,840
Speaker 2: back at least to like the fifteenth cent as like

64
00:03:00,880 --> 00:03:05,000
Speaker 2: a hunting cry, right when somebody was like somebody else

65
00:03:05,080 --> 00:03:10,720
Speaker 2: might go yo, and you'd go chase fox. That was

66
00:03:11,160 --> 00:03:14,440
Speaker 2: kind of the first wave of yo. As far back

67
00:03:14,480 --> 00:03:18,399
Speaker 2: as eighteen fifty nine. We know that there were sailors

68
00:03:18,400 --> 00:03:19,320
Speaker 2: that were using.

69
00:03:19,080 --> 00:03:21,400
Speaker 1: It yoho ho, yoho ho.

70
00:03:21,840 --> 00:03:26,920
Speaker 2: Or also it was a response for a roll call

71
00:03:27,440 --> 00:03:30,760
Speaker 2: like yo, like somebody called your name, you would say yo, key.

72
00:03:31,280 --> 00:03:34,079
Speaker 2: It wasn't until after World War Two, though, that the

73
00:03:34,120 --> 00:03:38,520
Speaker 2: modern incarnation comes and it came out of the Italian

74
00:03:38,920 --> 00:03:40,280
Speaker 2: quarters of Philadelphia.

75
00:03:40,400 --> 00:03:41,040
Speaker 1: Of course it did.

76
00:03:41,520 --> 00:03:43,840
Speaker 2: So that's where they think yo came from after World

77
00:03:43,880 --> 00:03:47,960
Speaker 2: War Two. Hence Eddie Murphy was wrong in using yo

78
00:03:48,640 --> 00:03:53,480
Speaker 2: especially frequently in the movie Harlem Nins. So I did

79
00:03:53,520 --> 00:03:56,840
Speaker 2: all that research, or I could have just looked into

80
00:03:57,000 --> 00:04:03,640
Speaker 2: Google Translate from English to Filipino or vice versas, okay,

81
00:04:04,000 --> 00:04:05,640
Speaker 2: and find that it just means come.

82
00:04:06,520 --> 00:04:08,160
Speaker 1: Yeah, but I don't think that's what it means here.

83
00:04:08,200 --> 00:04:09,040
Speaker 1: It does it?

84
00:04:09,040 --> 00:04:09,760
Speaker 2: It does now?

85
00:04:09,920 --> 00:04:10,280
Speaker 1: Okay.

86
00:04:10,480 --> 00:04:14,000
Speaker 2: So the word yo yo, as it stands right means come,

87
00:04:14,000 --> 00:04:15,120
Speaker 2: come or come back.

88
00:04:15,320 --> 00:04:16,159
Speaker 1: Yeah, that makes sense.

89
00:04:16,400 --> 00:04:19,960
Speaker 2: Did you know that I did? You want to talk

90
00:04:20,000 --> 00:04:21,760
Speaker 2: a little bit about the history of yo yos? Did

91
00:04:21,760 --> 00:04:27,480
Speaker 2: you know before reading this fantastic article that yo yo's originated,

92
00:04:27,560 --> 00:04:30,120
Speaker 2: as we understand them now, originated in the Philippines in

93
00:04:30,160 --> 00:04:31,120
Speaker 2: the nineteen twenties.

94
00:04:32,120 --> 00:04:34,039
Speaker 1: I didn't know that. I did know that it was

95
00:04:34,320 --> 00:04:37,000
Speaker 1: around for a long time before that, though, in you know,

96
00:04:37,200 --> 00:04:39,640
Speaker 1: other forms.

97
00:04:39,200 --> 00:04:41,120
Speaker 2: Well pretty much the same form. There were like two

98
00:04:41,160 --> 00:04:44,240
Speaker 2: forms of yo yo's in history. Yeah, and one came

99
00:04:44,279 --> 00:04:46,000
Speaker 2: out of the New one came out of the Philippines.

100
00:04:46,240 --> 00:04:48,479
Speaker 2: The other one, Yeah, it was pretty old.

101
00:04:48,279 --> 00:04:52,160
Speaker 1: Well, ancient Chinese or at least ancient Greeks, right more

102
00:04:52,200 --> 00:04:55,080
Speaker 1: than twenty five hundred years ago. But they think the

103
00:04:55,160 --> 00:04:56,880
Speaker 1: Chinese had something similar to that.

104
00:04:57,080 --> 00:04:59,800
Speaker 2: Yeah, I'm starting to strongly suspect that the Chinese or

105
00:04:59,800 --> 00:05:03,560
Speaker 2: the origin of human civilization. You think, yeah, they came

106
00:05:03,640 --> 00:05:06,360
Speaker 2: up with beer. Yeah, well they came up with beer.

107
00:05:07,360 --> 00:05:09,360
Speaker 2: There you have it. They went right there.

108
00:05:09,560 --> 00:05:11,799
Speaker 1: And it is the oldest toy on the planet except

109
00:05:11,920 --> 00:05:13,200
Speaker 1: the doll. The dolly.

110
00:05:13,320 --> 00:05:16,040
Speaker 2: I thought that was pretty interesting too. Yeah, yeah, of course,

111
00:05:16,560 --> 00:05:18,760
Speaker 2: although I wonder if they're kind of diminishing any kind

112
00:05:18,800 --> 00:05:21,560
Speaker 2: of ancient rituals or rites by saying, like, look at

113
00:05:21,560 --> 00:05:24,039
Speaker 2: this cute doll, when really it's you know, some sort

114
00:05:24,080 --> 00:05:24,640
Speaker 2: of fetish.

115
00:05:26,839 --> 00:05:29,120
Speaker 1: I don't know, you never know. So it's been around

116
00:05:29,160 --> 00:05:32,040
Speaker 1: a long time. They've designed it in different ways over

117
00:05:32,080 --> 00:05:37,440
Speaker 1: the years. The original design was had the string tied

118
00:05:37,680 --> 00:05:40,400
Speaker 1: tight to the little axis there.

119
00:05:40,600 --> 00:05:42,960
Speaker 2: We'll call it the Greek design, the Greek design, No,

120
00:05:43,040 --> 00:05:46,240
Speaker 2: we'll call it the Chinese design or the European design.

121
00:05:46,480 --> 00:05:48,840
Speaker 1: Well, not design, but it was popular in Europe. Yeah,

122
00:05:48,880 --> 00:05:52,040
Speaker 1: and that obviously if you ever used an old yo

123
00:05:52,080 --> 00:05:55,120
Speaker 1: yo like that, or redesign yours to where it's tied

124
00:05:55,120 --> 00:05:57,960
Speaker 1: around the axle. It'll pop up, you know, as soon

125
00:05:57,960 --> 00:06:00,320
Speaker 1: as you throw it down, it'll pop back up. Yeah,

126
00:06:00,320 --> 00:06:01,960
Speaker 1: because it's tied to the axle.

127
00:06:01,920 --> 00:06:05,440
Speaker 2: Exactly right. And you said it was popular in Europe.

128
00:06:05,440 --> 00:06:07,920
Speaker 2: There were other words for other names for the yo

129
00:06:08,000 --> 00:06:10,080
Speaker 2: yo before it was a yo yo.

130
00:06:10,240 --> 00:06:10,760
Speaker 1: That's right.

131
00:06:10,960 --> 00:06:14,720
Speaker 2: There was the limigrette, the bandolore.

132
00:06:14,960 --> 00:06:18,240
Speaker 1: The bandolora was British, I believe the quiz. Yeah, I

133
00:06:18,560 --> 00:06:21,040
Speaker 1: didn't get a country of origin for that, but.

134
00:06:21,320 --> 00:06:23,400
Speaker 2: It was very popular in Europe. There's a painting of

135
00:06:23,560 --> 00:06:26,640
Speaker 2: I think Louis the eighteenth is he the boy king?

136
00:06:27,360 --> 00:06:29,320
Speaker 2: I don't know whichever Louis was the boy king of

137
00:06:29,400 --> 00:06:32,360
Speaker 2: him holding like a yo yo, like a royal painting

138
00:06:32,400 --> 00:06:33,280
Speaker 2: of him with a yo yo?

139
00:06:33,600 --> 00:06:35,839
Speaker 1: Or the what was a little hoop on in a stick?

140
00:06:36,360 --> 00:06:37,320
Speaker 2: I think that's what it was called.

141
00:06:37,320 --> 00:06:38,359
Speaker 1: That was an awesome game.

142
00:06:38,200 --> 00:06:43,880
Speaker 2: The hoop on a stick. And then I don't think

143
00:06:43,960 --> 00:06:45,919
Speaker 2: you can compare the yo yo to the hoop on

144
00:06:45,960 --> 00:06:46,440
Speaker 2: a stick.

145
00:06:46,640 --> 00:06:48,520
Speaker 1: No, I'm not comparing it. I'm just saying I just

146
00:06:48,560 --> 00:06:50,400
Speaker 1: never got that toy.

147
00:06:50,760 --> 00:06:53,120
Speaker 2: Oh oh, okay, well, here's another one for you. Napoleon

148
00:06:53,360 --> 00:06:55,760
Speaker 2: was well known for carrying and using a yo yo,

149
00:06:56,400 --> 00:06:58,039
Speaker 2: apparently for stress relief.

150
00:06:58,520 --> 00:06:59,880
Speaker 1: Oh yeah, yeah, it didn't work too.

151
00:07:00,160 --> 00:07:02,960
Speaker 2: Here's a stressed out dude. Yeah he needed the yo yo.

152
00:07:03,440 --> 00:07:07,520
Speaker 2: But as you said that, that's the European favored or

153
00:07:07,839 --> 00:07:10,480
Speaker 2: Chinese design, where like the strings tied really tight to

154
00:07:10,520 --> 00:07:12,320
Speaker 2: the axle and it just basically goes up and down.

155
00:07:12,440 --> 00:07:12,680
Speaker 1: Yeah.

156
00:07:12,800 --> 00:07:16,640
Speaker 2: Right, So the Filipino design led to the modern yo

157
00:07:16,720 --> 00:07:19,840
Speaker 2: yo as we understand it now, And the huge distinction

158
00:07:20,720 --> 00:07:24,400
Speaker 2: is that the string is just looped around the axle

159
00:07:24,560 --> 00:07:28,000
Speaker 2: kind of loosely, yeah, which has the added benefit of

160
00:07:28,080 --> 00:07:32,360
Speaker 2: allowing the yo yo itself to spin once it reaches

161
00:07:32,400 --> 00:07:33,760
Speaker 2: the end of the string. Yeah.

162
00:07:34,480 --> 00:07:37,800
Speaker 1: Sleep, that's what the that's why people yo yo, I think. Yeah,

163
00:07:37,840 --> 00:07:39,400
Speaker 1: it's all about the tricks. I mean, it's sort of

164
00:07:39,400 --> 00:07:41,160
Speaker 1: fun for a minute just to go up and down,

165
00:07:41,720 --> 00:07:43,360
Speaker 1: but it's really all about the tricks.

166
00:07:43,120 --> 00:07:45,000
Speaker 2: Right, It's just a stress reliever if it just goes

167
00:07:45,080 --> 00:07:45,520
Speaker 2: up and down.

168
00:07:45,560 --> 00:07:46,960
Speaker 1: Did you yo yo when you were a kid?

169
00:07:47,200 --> 00:07:49,560
Speaker 2: Uh? Yeah, here there. But even as a kid, like

170
00:07:49,600 --> 00:07:52,320
Speaker 2: I could sense that like these these new modern ones

171
00:07:52,320 --> 00:07:54,480
Speaker 2: that we'll talk about with like ball bearings and clutches.

172
00:07:54,560 --> 00:07:55,600
Speaker 2: They just seem like cheating.

173
00:07:56,520 --> 00:08:00,200
Speaker 1: I agree, let's not even talk about them. It's not

174
00:08:00,240 --> 00:08:01,080
Speaker 1: even a real yo yo.

175
00:08:01,480 --> 00:08:03,600
Speaker 2: So, Chuck, you want to talk about a little bit

176
00:08:03,640 --> 00:08:04,400
Speaker 2: about physics.

177
00:08:04,560 --> 00:08:07,080
Speaker 1: Well, let's finish the history first, shall we. Oh?

178
00:08:07,080 --> 00:08:08,280
Speaker 2: Okay, well, I have plenty of that.

179
00:08:09,480 --> 00:08:12,120
Speaker 1: It was originally in the Philippines. They think it was

180
00:08:12,120 --> 00:08:14,560
Speaker 1: a hunting weapon for like four hundred years. Uh huh so,

181
00:08:15,440 --> 00:08:17,560
Speaker 1: but not like a little tiny yo yo. They were

182
00:08:17,600 --> 00:08:21,120
Speaker 1: really big and it was basically a big spindle attached

183
00:08:21,160 --> 00:08:23,680
Speaker 1: to a rope with like spikes coming off of it.

184
00:08:23,800 --> 00:08:25,480
Speaker 2: They were like the size of a you go, yeah,

185
00:08:25,480 --> 00:08:26,200
Speaker 2: And I guess.

186
00:08:25,960 --> 00:08:28,880
Speaker 1: The just the benefit there is you could get it

187
00:08:28,960 --> 00:08:30,600
Speaker 1: back after you threw it at somebody.

188
00:08:31,200 --> 00:08:34,000
Speaker 2: Right. The string was almost just useless though, Well could

189
00:08:34,000 --> 00:08:35,439
Speaker 2: you just throw it and run after it?

190
00:08:35,679 --> 00:08:39,240
Speaker 1: Oh? Really? Okay? It was actually heavy rope and they

191
00:08:39,280 --> 00:08:41,319
Speaker 1: use it for hunting too, right.

192
00:08:41,400 --> 00:08:44,880
Speaker 2: Well, at some point down the line, well, yeah, you

193
00:08:44,880 --> 00:08:47,440
Speaker 2: would think anything used in hunting, you know, does double

194
00:08:47,520 --> 00:08:54,199
Speaker 2: duty and more exactly anything you're trying to kill. Yeah.

195
00:08:54,360 --> 00:08:57,199
Speaker 2: At some point though, they became smaller and became toys,

196
00:08:57,880 --> 00:09:01,080
Speaker 2: and in the twenties a Philip you know, immigrant to

197
00:09:01,080 --> 00:09:05,120
Speaker 2: the US named Pedro Flores, started a company, the first

198
00:09:05,440 --> 00:09:08,559
Speaker 2: modern yoyo company in the United States, and did pretty

199
00:09:08,559 --> 00:09:11,400
Speaker 2: well for himself. And then in nineteen twenty nine he

200
00:09:11,440 --> 00:09:14,680
Speaker 2: sold out to a man named Duncan, Right, Donald.

201
00:09:14,360 --> 00:09:20,920
Speaker 1: Duncan, Yes, Donald Duncan, and Duncan Duncan, and you know

202
00:09:20,960 --> 00:09:23,320
Speaker 1: Floris's in Santa Barbara, and like you said, was selling

203
00:09:23,320 --> 00:09:26,439
Speaker 1: these things like hotcakes enough that Duncan said, hey, let

204
00:09:26,480 --> 00:09:28,960
Speaker 1: me buy that. I'm going to keep the name yo

205
00:09:29,000 --> 00:09:32,320
Speaker 1: yo because it's catchy. Yeah, I'm going to trademarkt and

206
00:09:32,360 --> 00:09:35,959
Speaker 1: now I own it. And through the years he had

207
00:09:35,960 --> 00:09:39,719
Speaker 1: competitors that made similar devices with different names, and they

208
00:09:39,720 --> 00:09:42,839
Speaker 1: were like, dude, everyone's calling the sing of yo yo.

209
00:09:43,360 --> 00:09:44,680
Speaker 1: We want to be able to call it a yo

210
00:09:44,760 --> 00:09:46,480
Speaker 1: yo too, And he said, no, no, I own it.

211
00:09:46,960 --> 00:09:49,880
Speaker 1: Then the federal courts in nineteen sixty five says, you

212
00:09:49,960 --> 00:09:52,559
Speaker 1: know what, that's generic enough now where you don't own

213
00:09:52,600 --> 00:09:54,920
Speaker 1: it any longer. Right, they're all yo yo's.

214
00:09:55,040 --> 00:09:58,600
Speaker 2: Well what those legal challenges to their trademark? The name

215
00:09:58,720 --> 00:10:01,760
Speaker 2: yoyo was one of the things that bled the company dry.

216
00:10:02,280 --> 00:10:06,239
Speaker 2: It eventually went bankrupt. Duncan, the Duncan Company went bankrupt.

217
00:10:06,520 --> 00:10:08,880
Speaker 1: Yeah, the same year they ruled, yeah against them.

218
00:10:08,880 --> 00:10:10,560
Speaker 2: They were like, well, that's it for us. But they

219
00:10:10,600 --> 00:10:13,719
Speaker 2: also had other money troubles. They were actually victims of

220
00:10:13,760 --> 00:10:16,640
Speaker 2: their own success. The Duncan Company was. So they moved

221
00:10:17,040 --> 00:10:20,320
Speaker 2: in the forties to luck, Wisconsin, which very quickly became

222
00:10:20,360 --> 00:10:23,080
Speaker 2: known as the yoyo capital of the world. And at

223
00:10:23,240 --> 00:10:26,760
Speaker 2: their peak they were making thirty six hundred yoyos an hour,

224
00:10:27,440 --> 00:10:30,160
Speaker 2: mostly out of wood at first maple. They were using

225
00:10:30,200 --> 00:10:34,400
Speaker 2: a million board feet of maple wood every year. Yeah,

226
00:10:34,440 --> 00:10:37,160
Speaker 2: it's a lot. And they actually, in addition to their

227
00:10:37,240 --> 00:10:41,000
Speaker 2: legal challenges, like the money going to fight their legal battles,

228
00:10:42,080 --> 00:10:46,120
Speaker 2: they were paying tons of money in overtime too, advertising

229
00:10:47,240 --> 00:10:50,120
Speaker 2: And as a matter of fact, I think in nineteen

230
00:10:50,200 --> 00:10:54,440
Speaker 2: sixty two, Chuck, they managed to sell forty five million

231
00:10:54,520 --> 00:10:57,080
Speaker 2: yo yos and in that same year there were only

232
00:10:57,160 --> 00:11:00,960
Speaker 2: forty million kids in the US. Wow, pretty astounding.

233
00:11:01,000 --> 00:11:02,760
Speaker 1: A chicken in every pot and a yo yo in

234
00:11:02,800 --> 00:11:07,760
Speaker 1: every other hand at least. Yeah, sure, well, lets I

235
00:11:07,800 --> 00:11:09,320
Speaker 1: guess some kids were yoyo with both hands.

236
00:11:09,440 --> 00:11:13,080
Speaker 2: They're rich kids. Yeah, But like I said, they the

237
00:11:13,240 --> 00:11:17,000
Speaker 2: company ended up coming bankrupt anyway. But Yoyo enthusiasts still

238
00:11:17,160 --> 00:11:21,240
Speaker 2: look very fondly on the Duncan name. And I think

239
00:11:21,360 --> 00:11:24,840
Speaker 2: June sixth, Yes, June sixth is National Yo Yo Day,

240
00:11:25,120 --> 00:11:29,280
Speaker 2: which happens to be the same day as Donald Duncan's birthday.

241
00:11:29,880 --> 00:11:32,600
Speaker 1: Yeah. Yeah, well, and the Duncan name lives on obviously,

242
00:11:32,640 --> 00:11:35,520
Speaker 1: you still see Duncan Yoyo's. They they sold out. They

243
00:11:35,520 --> 00:11:36,960
Speaker 1: didn't just shut down.

244
00:11:37,280 --> 00:11:40,320
Speaker 2: Well, they went bankrupts and sold out, right, yeah yeah.

245
00:11:39,880 --> 00:11:44,560
Speaker 1: So who was it? The flam Flambeo Plastics company. Yeah,

246
00:11:44,600 --> 00:11:47,200
Speaker 1: they said we'll keep the name Duncan because it's synonymous

247
00:11:47,200 --> 00:11:47,800
Speaker 1: with Yo yo's.

248
00:11:47,880 --> 00:12:10,960
Speaker 2: Yeah, it's not generic yet. No, No, there's a little

249
00:12:11,000 --> 00:12:13,080
Speaker 2: yoyo history for you. Yeah, I got a little more.

250
00:12:13,120 --> 00:12:15,960
Speaker 2: I'm gonna say to the end. I think you'll like. Okay,

251
00:12:16,559 --> 00:12:17,640
Speaker 2: we're gonna tease you with it.

252
00:12:17,880 --> 00:12:19,240
Speaker 1: Now, let's talk about physics.

253
00:12:19,400 --> 00:12:21,600
Speaker 2: Well, I think this is very interesting.

254
00:12:21,960 --> 00:12:22,240
Speaker 1: Good.

255
00:12:24,440 --> 00:12:29,080
Speaker 2: So there's a two Okay you mentioned with the string

256
00:12:29,200 --> 00:12:32,600
Speaker 2: tied to the classic Chinese design Yo yo, you have

257
00:12:32,800 --> 00:12:38,480
Speaker 2: one kind of energy going on, right, Yes, and that

258
00:12:38,679 --> 00:12:42,400
Speaker 2: is linear momentum, the ability of it to go up

259
00:12:42,520 --> 00:12:45,559
Speaker 2: and down I should say down and up right, that's right.

260
00:12:45,880 --> 00:12:49,240
Speaker 2: With the Filipino design the modern design. It has two

261
00:12:49,280 --> 00:12:52,760
Speaker 2: kinds of potential energy. It has that same linear momentum

262
00:12:52,840 --> 00:12:55,360
Speaker 2: to go up and down, but it also has angular momentum.

263
00:12:55,440 --> 00:13:00,400
Speaker 2: And angular momentum is its ability to spin on an axle. Yeah, okay,

264
00:13:00,559 --> 00:13:03,120
Speaker 2: so you've got two things going on. And like you said,

265
00:13:03,280 --> 00:13:05,840
Speaker 2: when the yo yo hits the end of the line

266
00:13:06,000 --> 00:13:08,839
Speaker 2: of its linear momentum, it can still It's built up

267
00:13:08,880 --> 00:13:11,360
Speaker 2: since it's wound around the spool. It's built up a

268
00:13:11,400 --> 00:13:13,560
Speaker 2: lot of angular momentum, so it can just sit there

269
00:13:13,600 --> 00:13:16,080
Speaker 2: and spin or sleep as you called it.

270
00:13:16,200 --> 00:13:19,560
Speaker 1: Yeah. It actually increases as it goes down, which is

271
00:13:19,600 --> 00:13:21,840
Speaker 1: the key to keeping it spinning.

272
00:13:22,000 --> 00:13:22,200
Speaker 2: Right.

273
00:13:22,280 --> 00:13:23,800
Speaker 1: It gets faster as it falls.

274
00:13:24,040 --> 00:13:26,240
Speaker 2: There's another pretty cool trait to a yo yo. Who

275
00:13:26,280 --> 00:13:29,400
Speaker 2: knew they were so complex? I didn't, did you?

276
00:13:29,679 --> 00:13:30,040
Speaker 1: I did not?

277
00:13:30,360 --> 00:13:36,040
Speaker 2: Okay. So they also have gyroscopic stability, chuck, they do. Okay. So,

278
00:13:36,080 --> 00:13:38,400
Speaker 2: if you have a yoyo that's sleeping and you push

279
00:13:38,440 --> 00:13:40,880
Speaker 2: down on top of it, like it goes down and

280
00:13:40,920 --> 00:13:44,840
Speaker 2: then back up right, that's because of its gyroscopic stability.

281
00:13:44,960 --> 00:13:47,199
Speaker 2: That point that you push down on the yo yo

282
00:13:48,040 --> 00:13:51,120
Speaker 2: is transferred from the front and spun around to the back.

283
00:13:51,240 --> 00:13:53,400
Speaker 2: So that's even now, so the yoyo will just keep

284
00:13:53,440 --> 00:13:55,240
Speaker 2: spinning as long as it's spinning fast enough.

285
00:13:55,640 --> 00:14:00,640
Speaker 1: Gyroscopic stability, Yes, that means a spinning object object will

286
00:14:00,640 --> 00:14:04,560
Speaker 1: resist change to its axis of rotation. And if you've

287
00:14:04,559 --> 00:14:07,880
Speaker 1: ever thrown a football, it's the same thing. Yeah, Or

288
00:14:07,880 --> 00:14:09,440
Speaker 1: if you've ever thrown a football poorly?

289
00:14:10,040 --> 00:14:13,320
Speaker 2: What do they call that wobbler? A turkey wounded duck?

290
00:14:13,400 --> 00:14:16,680
Speaker 1: Brick? That's why winded duck doesn't go very far because

291
00:14:16,720 --> 00:14:19,080
Speaker 1: it doesn't have that tight spin. Yeah, so it falls

292
00:14:19,080 --> 00:14:20,720
Speaker 1: off its axis and won't travel as.

293
00:14:20,600 --> 00:14:22,560
Speaker 2: Far, exactly same as a prison And then the whole

294
00:14:22,560 --> 00:14:23,080
Speaker 2: team's mad.

295
00:14:23,440 --> 00:14:27,760
Speaker 1: Basically anything that spins, Yeah, Frisbee's football's there's there's got

296
00:14:27,800 --> 00:14:30,360
Speaker 1: to be a baseball. We could liken it to a

297
00:14:30,360 --> 00:14:31,080
Speaker 1: baseball somehow.

298
00:14:31,160 --> 00:14:34,520
Speaker 2: Let's say a curveball, knuckleball slider.

299
00:14:34,280 --> 00:14:37,440
Speaker 1: Definitely not a knuckleball slighter doesn't spin it all, really,

300
00:14:38,200 --> 00:14:40,640
Speaker 1: is it like a shot put? No, the knuckleball, you,

301
00:14:41,040 --> 00:14:44,080
Speaker 1: the whole key is it doesn't move. It travels like this,

302
00:14:44,400 --> 00:14:47,600
Speaker 1: and that's why it moves all around. Crazy, isn't that nutty?

303
00:14:47,680 --> 00:14:52,520
Speaker 2: Yeah, So you've got your you've got your yo yo sleeping,

304
00:14:53,160 --> 00:14:58,560
Speaker 2: You're you're totally aware of its gyroscopic stability and you

305
00:14:58,680 --> 00:15:03,000
Speaker 2: understand that it's angle momentum is just awesome. It's far

306
00:15:03,040 --> 00:15:05,600
Speaker 2: out right, it's far out but you want to wake

307
00:15:05,680 --> 00:15:07,520
Speaker 2: it up. And that's when you bring it out of

308
00:15:07,520 --> 00:15:10,520
Speaker 2: its sleep and rewind it back up the spool.

309
00:15:10,400 --> 00:15:12,000
Speaker 1: Right, a little tug on the old finger.

310
00:15:12,160 --> 00:15:15,040
Speaker 2: Yeah, And the reason why is because the loop, right,

311
00:15:15,400 --> 00:15:19,120
Speaker 2: there's less friction with the loop around the axle. Yeah,

312
00:15:19,200 --> 00:15:21,760
Speaker 2: when you tug it, you increase that friction and you

313
00:15:21,800 --> 00:15:23,080
Speaker 2: allow it to rewind.

314
00:15:23,200 --> 00:15:25,520
Speaker 1: It just grabs a hold of its buddy and just

315
00:15:25,640 --> 00:15:26,920
Speaker 1: let's go back up to the palm.

316
00:15:27,120 --> 00:15:30,680
Speaker 2: Yep. It's pretty cool. Yeah, I like yoyo physics a lot.

317
00:15:32,840 --> 00:15:35,800
Speaker 2: So we basically just talked about the two hardest parts, right,

318
00:15:36,640 --> 00:15:37,720
Speaker 2: sleeping and waking.

319
00:15:37,960 --> 00:15:41,000
Speaker 1: Yeah, And like I said, sleeping is the key to

320
00:15:41,080 --> 00:15:44,800
Speaker 1: do any kind of trick like walking the dog, which

321
00:15:45,040 --> 00:15:46,320
Speaker 1: I was pretty good. I used to could do a

322
00:15:46,360 --> 00:15:48,840
Speaker 1: few yo yo tricks. Really, Yeah, I could walk the dog,

323
00:15:48,880 --> 00:15:51,640
Speaker 1: and I could do I could do the deal where

324
00:15:51,640 --> 00:15:55,560
Speaker 1: you make a triangle and then TikTok through the triangle,

325
00:15:55,800 --> 00:15:56,400
Speaker 1: something like.

326
00:15:56,360 --> 00:16:00,680
Speaker 2: A cradle or probably the cats in the cradle, let's.

327
00:16:00,440 --> 00:16:02,440
Speaker 1: Call a cat's cradle, and then I could I could

328
00:16:03,200 --> 00:16:05,840
Speaker 1: do the around the world. Wow, around the world.

329
00:16:06,000 --> 00:16:07,160
Speaker 2: Yeah, I couldn't do any of those.

330
00:16:07,240 --> 00:16:09,240
Speaker 1: I'm gonna this inspired me to get a new Yo Yo.

331
00:16:09,360 --> 00:16:11,800
Speaker 2: By the way, I like the vintage dunk and one

332
00:16:11,880 --> 00:16:14,720
Speaker 2: specifically the yellow ones with the butterfly, like the gold

333
00:16:15,080 --> 00:16:16,520
Speaker 2: the gold butterfly.

334
00:16:16,240 --> 00:16:17,200
Speaker 1: The inverted ones.

335
00:16:18,400 --> 00:16:21,200
Speaker 2: No, it was the one butterfly on that okay, because

336
00:16:21,240 --> 00:16:23,640
Speaker 2: they had those that were that looked like a butterfly

337
00:16:23,800 --> 00:16:26,200
Speaker 2: that were I know what you're talking about, inverted, and

338
00:16:26,240 --> 00:16:30,239
Speaker 2: I think that actually plays a part in the uh

339
00:16:31,640 --> 00:16:34,800
Speaker 2: uh increasing the moment of inertia section. Yeah, I think

340
00:16:34,840 --> 00:16:36,840
Speaker 2: that's why they flipped it out to put more weight

341
00:16:36,880 --> 00:16:39,280
Speaker 2: on the outside. Yeah, okay, you want to talk about that?

342
00:16:39,320 --> 00:16:39,560
Speaker 1: Why not?

343
00:16:39,800 --> 00:16:43,720
Speaker 2: So do you remember when we did the Murphy's Law podcast?

344
00:16:44,160 --> 00:16:44,880
Speaker 1: How could I forget?

345
00:16:44,920 --> 00:16:46,800
Speaker 2: Remember one of the books that he wrote was for

346
00:16:46,840 --> 00:16:48,040
Speaker 2: your Moments of Inertia?

347
00:16:48,520 --> 00:16:48,920
Speaker 1: Yeah?

348
00:16:49,000 --> 00:16:51,720
Speaker 2: Yeah, I didn't realize it was a terrible, terrible engineering

349
00:16:51,800 --> 00:16:53,760
Speaker 2: pun until I read this article.

350
00:16:53,920 --> 00:16:54,120
Speaker 1: Yeah.

351
00:16:54,280 --> 00:16:56,560
Speaker 2: Kind of made me hate John Paul Stapp a little bit.

352
00:16:56,720 --> 00:16:57,800
Speaker 1: Nah, we love that guy.

353
00:16:58,160 --> 00:17:01,760
Speaker 2: So chuck A moment of Inertia's basically a way of

354
00:17:01,800 --> 00:17:07,880
Speaker 2: describing a spinning objects resistance to changes in that rotation,

355
00:17:08,080 --> 00:17:14,359
Speaker 2: basically being slowed down. Yeah, right, And what smarter people

356
00:17:14,400 --> 00:17:16,960
Speaker 2: than us have figured out is that if you increase

357
00:17:17,040 --> 00:17:21,960
Speaker 2: the mass and distribute it slightly further away from the axis,

358
00:17:22,640 --> 00:17:26,439
Speaker 2: you're going to increase its moment of inertia, right, and

359
00:17:26,480 --> 00:17:29,360
Speaker 2: that increases the amount of time it's just sleeping, right.

360
00:17:30,040 --> 00:17:32,000
Speaker 1: Yeah. And like I said, I don't know this, but

361
00:17:32,040 --> 00:17:34,040
Speaker 1: I just remember when I was a kid, they had

362
00:17:34,080 --> 00:17:36,640
Speaker 1: those inverted yo yos, and I bet you anything that's

363
00:17:36,640 --> 00:17:38,320
Speaker 1: why they did that. It's got to be because they

364
00:17:38,320 --> 00:17:42,000
Speaker 1: were wider at the outside and then curved in, which

365
00:17:42,200 --> 00:17:44,760
Speaker 1: had to be less mass. Yeah, it was less stuff,

366
00:17:45,160 --> 00:17:48,240
Speaker 1: less wood, right, So I'm going to go on record

367
00:17:48,240 --> 00:17:49,360
Speaker 1: as saying that's why they did that.

368
00:17:49,600 --> 00:17:53,840
Speaker 2: But I think you want more mass further away, yeah,

369
00:17:53,960 --> 00:17:55,399
Speaker 2: to increase its moment of inertia.

370
00:17:55,480 --> 00:17:57,439
Speaker 1: Right. Yeah, So it was there was more mass on

371
00:17:57,480 --> 00:18:00,320
Speaker 1: the outside, I guess, further away from the axis, right. Yeah.

372
00:18:00,480 --> 00:18:03,280
Speaker 2: So that allows things to sleep a lot longer. And

373
00:18:04,040 --> 00:18:06,439
Speaker 2: that was a I guess you could say one of

374
00:18:06,480 --> 00:18:09,919
Speaker 2: the breakthroughs in yoyo design. I think in the sixties,

375
00:18:10,119 --> 00:18:14,199
Speaker 2: they started adding mass to the outside and extending the

376
00:18:14,240 --> 00:18:17,000
Speaker 2: axle a little bit. Bam, the yoyo has been improved.

377
00:18:17,119 --> 00:18:21,520
Speaker 2: Think about this, right, twenty five hundred, maybe even longer

378
00:18:21,560 --> 00:18:25,600
Speaker 2: than that. Years ago. Yeah, somebody invented the yoyo. Does

379
00:18:25,600 --> 00:18:29,680
Speaker 2: not change until the Philippines in the early twentieth century.

380
00:18:29,840 --> 00:18:31,639
Speaker 1: Well, I thought it said it did change, We just

381
00:18:31,680 --> 00:18:36,240
Speaker 1: don't know. Said there were changes in designs over the years. No,

382
00:18:36,320 --> 00:18:38,080
Speaker 1: not that I took. I took it like there was

383
00:18:38,200 --> 00:18:41,440
Speaker 1: one way, and then there was the Filipino way.

384
00:18:42,160 --> 00:18:42,920
Speaker 2: And that was it.

385
00:18:43,240 --> 00:18:44,600
Speaker 1: We got a correction to make then.

386
00:18:44,600 --> 00:18:46,760
Speaker 2: And then the twentieth century hits, and then there's all

387
00:18:46,800 --> 00:18:48,800
Speaker 2: these great improvements on these designs.

388
00:18:49,680 --> 00:18:51,160
Speaker 1: Indeed, one of the.

389
00:18:51,040 --> 00:18:55,920
Speaker 2: Improvements, Chuck was adding ball bearings. Right, yeah, well, you.

390
00:18:55,880 --> 00:18:58,360
Speaker 1: And I don't think these are improvements, ear least I don't.

391
00:18:58,560 --> 00:19:02,000
Speaker 2: Okay, that's absolutely sure. That's a good caveat. I think

392
00:19:02,040 --> 00:19:05,119
Speaker 2: that the Filipinos perfected the yoya.

393
00:19:05,240 --> 00:19:08,320
Speaker 1: Let's just call them modifications, okay for sorry kids who

394
00:19:08,320 --> 00:19:10,920
Speaker 1: don't know how to yoyo rich kids. Yeah, that makes

395
00:19:10,920 --> 00:19:13,760
Speaker 1: it easier, I think, Yeah, and that the whole point

396
00:19:13,800 --> 00:19:16,240
Speaker 1: of both of these things. Yeah, I guess it makes

397
00:19:16,240 --> 00:19:17,920
Speaker 1: it easier sleep and yeah.

398
00:19:17,760 --> 00:19:20,480
Speaker 2: Yeah, And I guess they're like, well, if you're just

399
00:19:20,640 --> 00:19:23,760
Speaker 2: enjoying sleeping and waking your yo yo, then why make

400
00:19:23,800 --> 00:19:24,560
Speaker 2: it tough.

401
00:19:24,400 --> 00:19:26,000
Speaker 1: If you want to have fun with your toy?

402
00:19:26,280 --> 00:19:26,560
Speaker 2: Right?

403
00:19:28,760 --> 00:19:30,399
Speaker 1: I can't believe they made it easier for kids to

404
00:19:30,480 --> 00:19:31,840
Speaker 1: have fun. It's not, dare they?

405
00:19:32,040 --> 00:19:36,240
Speaker 2: So the ball bearing design I think is kind of clever. Basically,

406
00:19:37,520 --> 00:19:42,040
Speaker 2: this modification takes the axle and splits it in two yeah,

407
00:19:42,119 --> 00:19:46,120
Speaker 2: into two races, which are basically little courses for ball

408
00:19:46,160 --> 00:19:47,159
Speaker 2: bearings to spin around.

409
00:19:47,400 --> 00:19:49,720
Speaker 1: Right, now, does it split the axle? These are just

410
00:19:49,760 --> 00:19:50,920
Speaker 1: around the axle.

411
00:19:51,080 --> 00:19:54,480
Speaker 2: So one is connected to the axle, right, that's the

412
00:19:54,560 --> 00:19:58,520
Speaker 2: inner race. One is connected to the string. That's the

413
00:19:58,560 --> 00:20:01,480
Speaker 2: outer race. And then in between the two ball bearings right, Okay,

414
00:20:02,119 --> 00:20:06,720
Speaker 2: they're not connected in any way except maybe via the

415
00:20:06,760 --> 00:20:08,120
Speaker 2: contact with the ball bearings.

416
00:20:08,280 --> 00:20:08,480
Speaker 1: Right.

417
00:20:08,880 --> 00:20:11,800
Speaker 2: So when you when you release your yo yo toward

418
00:20:11,840 --> 00:20:14,639
Speaker 2: the ground and it's linear and angular, momentum really build up.

419
00:20:15,280 --> 00:20:18,560
Speaker 2: When it hits the inner race can tilt a little

420
00:20:18,560 --> 00:20:23,080
Speaker 2: bit and connect with the outer race via the ball bearings.

421
00:20:23,160 --> 00:20:26,720
Speaker 2: So they're they're spinning right, right, and then as they

422
00:20:26,760 --> 00:20:31,800
Speaker 2: straighten out the they they're they're not connected anymore, so

423
00:20:31,840 --> 00:20:35,679
Speaker 2: that the string no longer has any effect on whether

424
00:20:35,760 --> 00:20:38,359
Speaker 2: the yo yo spins or not, because it's just the

425
00:20:38,520 --> 00:20:42,200
Speaker 2: inner race connected to the axle that's spinning. So your

426
00:20:42,320 --> 00:20:44,879
Speaker 2: yo yo can sleep far, far longer.

427
00:20:45,000 --> 00:20:47,200
Speaker 1: Yeah, the outer race spends the inner race which spins

428
00:20:47,200 --> 00:20:47,639
Speaker 1: the axle.

429
00:20:47,760 --> 00:20:50,159
Speaker 2: Right, it's like a transfer of angular momentum exactly, and

430
00:20:50,160 --> 00:20:52,080
Speaker 2: then the strings just like you just let me know

431
00:20:52,119 --> 00:20:54,240
Speaker 2: when you're done, and we'll wind back up.

432
00:20:54,560 --> 00:20:56,440
Speaker 1: Well, it'll get a little tougg'll do the same thing

433
00:20:56,440 --> 00:20:59,200
Speaker 1: with that style, right right, okay.

434
00:20:58,840 --> 00:21:01,520
Speaker 2: Or you can just completely take yourself out of the

435
00:21:01,560 --> 00:21:04,720
Speaker 2: equation altogether except for a snap of the risk. The

436
00:21:04,760 --> 00:21:07,920
Speaker 2: initial release is all you need to do with what's

437
00:21:07,960 --> 00:21:09,720
Speaker 2: called the yo yo with the brain.

438
00:21:10,600 --> 00:21:14,040
Speaker 1: These are really fake yoyo's. Yeah, I want to get

439
00:21:14,080 --> 00:21:14,840
Speaker 1: one though. It's kind of cool.

440
00:21:14,960 --> 00:21:16,919
Speaker 2: You could be in a vegetative state and do this

441
00:21:17,000 --> 00:21:17,320
Speaker 2: yo yo.

442
00:21:17,600 --> 00:21:21,240
Speaker 1: Yeah. This was in the nineties. Company called Yomega release these,

443
00:21:21,920 --> 00:21:24,119
Speaker 1: and they called it the yo Yo with a brain,

444
00:21:24,440 --> 00:21:26,080
Speaker 1: when in fact they should have called it the yo

445
00:21:26,160 --> 00:21:30,120
Speaker 1: Yo with a clutch. And the deal here is you've

446
00:21:30,119 --> 00:21:34,720
Speaker 1: got these two clutch arms weighted ball on one side,

447
00:21:34,720 --> 00:21:36,640
Speaker 1: and it's not attached on the other side, and they're

448
00:21:36,680 --> 00:21:40,800
Speaker 1: spring loaded. The spindle is not attached to the axle,

449
00:21:41,400 --> 00:21:44,159
Speaker 1: but the clutch arms are attached to the spindle. So

450
00:21:44,200 --> 00:21:47,520
Speaker 1: when you throw this thing down, it's gonna spin slower

451
00:21:47,560 --> 00:21:51,280
Speaker 1: at first, and the clutch is engaged. As it gets faster,

452
00:21:51,480 --> 00:21:55,080
Speaker 1: all of a sudden, it's enough inertia to pop the

453
00:21:55,080 --> 00:21:59,720
Speaker 1: clutch essentially against the edges, and it releases the spindle,

454
00:22:01,440 --> 00:22:03,600
Speaker 1: which makes the whole thing spin faster.

455
00:22:04,200 --> 00:22:08,800
Speaker 2: On the axis right, the centrifugal force pushes down the weight,

456
00:22:09,119 --> 00:22:12,520
Speaker 2: which pushes down the arm onto the spring, which releases

457
00:22:12,600 --> 00:22:14,280
Speaker 2: the two which allows it to spin.

458
00:22:14,680 --> 00:22:16,360
Speaker 1: And it only spins for a certain amount of time.

459
00:22:16,400 --> 00:22:18,360
Speaker 1: It's not like the kind that you tug back up.

460
00:22:18,760 --> 00:22:21,399
Speaker 1: It'll spin till it slows down and then the clutch

461
00:22:21,600 --> 00:22:24,080
Speaker 1: locks back down and boom, it shoots.

462
00:22:23,720 --> 00:22:24,600
Speaker 2: Back up right back.

463
00:22:25,280 --> 00:22:26,600
Speaker 1: I want to I wish we had one of those.

464
00:22:26,600 --> 00:22:27,480
Speaker 1: I want to see what it's like.

465
00:22:27,840 --> 00:22:30,760
Speaker 2: So basically, the big to the two modifications are based

466
00:22:30,800 --> 00:22:35,600
Speaker 2: on separating the string from the axle. Yeah, by creating

467
00:22:35,640 --> 00:22:39,159
Speaker 2: two different kinds of I guess axles or spindles or whatever.

468
00:22:39,280 --> 00:22:43,879
Speaker 1: Which are really just sort of taking the Philippine Filipino

469
00:22:43,920 --> 00:22:47,080
Speaker 1: design a step further because although it made contact with

470
00:22:47,119 --> 00:22:49,880
Speaker 1: the axle, it wasn't quote connected to the axle. Yeah,

471
00:22:49,960 --> 00:22:51,800
Speaker 1: I guess it was, but it wasn't tight right.

472
00:22:52,160 --> 00:22:54,160
Speaker 2: And a guy named Michael Caffrey is the one who

473
00:22:54,640 --> 00:22:56,600
Speaker 2: came up with the yo yo with the brain, and

474
00:22:56,760 --> 00:22:59,159
Speaker 2: Yomega started telling him in nineteen ninety, but he came

475
00:22:59,240 --> 00:23:03,000
Speaker 2: up with it nineteen two years after a man named

476
00:23:03,000 --> 00:23:06,520
Speaker 2: Tom Cune created the no Jive three and one yo

477
00:23:06,560 --> 00:23:09,080
Speaker 2: Yo that you could take apart and replace the axle

478
00:23:09,160 --> 00:23:12,480
Speaker 2: and do all sorts of modifications with no really big,

479
00:23:12,600 --> 00:23:15,320
Speaker 2: big time for changes in yo yo design.

480
00:23:15,480 --> 00:23:17,400
Speaker 1: So did he rip this dude off? Is that what you're saying?

481
00:23:17,560 --> 00:23:20,040
Speaker 2: No, okay, No, I'm just saying, like the two these

482
00:23:20,080 --> 00:23:23,359
Speaker 2: two big steps in the Yoyo design.

483
00:23:23,440 --> 00:23:26,440
Speaker 1: Well you said two years after it was sinister. Well

484
00:23:26,480 --> 00:23:28,720
Speaker 1: you're a very suspicious person I am when it comes

485
00:23:28,760 --> 00:23:32,200
Speaker 1: to yo Yo's design.

486
00:23:53,200 --> 00:23:56,680
Speaker 2: Chuck, that's pretty much the physics of yo Yo's Did

487
00:23:56,720 --> 00:23:59,400
Speaker 2: you know that we just explained how Yoyo's work.

488
00:23:59,640 --> 00:24:02,879
Speaker 1: You know, I looked online at videos and stuff to

489
00:24:02,960 --> 00:24:05,200
Speaker 1: make it a little easier because this is a very

490
00:24:05,480 --> 00:24:08,560
Speaker 1: visual thing, and they do have videos. But what I

491
00:24:08,640 --> 00:24:12,040
Speaker 1: found out is that a lot of teachers, physics teachers,

492
00:24:12,400 --> 00:24:16,960
Speaker 1: use yoyo's to describe these whatever four to six properties

493
00:24:17,000 --> 00:24:17,680
Speaker 1: that we described.

494
00:24:17,760 --> 00:24:20,920
Speaker 2: I have to tell you, I understand angular momentum far better.

495
00:24:21,000 --> 00:24:23,760
Speaker 1: Now. I understand, and although it went through the yoyos

496
00:24:23,760 --> 00:24:28,040
Speaker 1: to the football, I understand the moment of inertia. Okay,

497
00:24:28,119 --> 00:24:32,040
Speaker 1: all right, is that moment of inertia? No, that's angular momentum,

498
00:24:32,119 --> 00:24:33,200
Speaker 1: angular momentum.

499
00:24:32,880 --> 00:24:33,879
Speaker 2: Spinning on an axis.

500
00:24:33,960 --> 00:24:34,120
Speaker 1: Yeah.

501
00:24:34,160 --> 00:24:36,360
Speaker 2: Yeah, Oh you were talking about the gyroscopic stability.

502
00:24:36,680 --> 00:24:38,520
Speaker 1: Yeah, there's what it was. See I get confused.

503
00:24:38,760 --> 00:24:41,080
Speaker 2: I did too, Chuck, it's physics, man, don't feel bad.

504
00:24:42,119 --> 00:24:44,440
Speaker 2: You want to know a couple more pieces of yoyo trivia?

505
00:24:44,520 --> 00:24:45,040
Speaker 1: Yeah, it's here.

506
00:24:45,320 --> 00:24:48,879
Speaker 2: In nineteen sixty eight, when Abby Hoffman of the Chicago

507
00:24:49,040 --> 00:24:55,399
Speaker 2: seven Yeah, was indicted or no, charged with contempt of

508
00:24:55,520 --> 00:25:01,160
Speaker 2: Congress when he started doing the Walk the Dog during

509
00:25:01,200 --> 00:25:04,919
Speaker 2: a House on American Activities Committee. Oh really session that

510
00:25:05,040 --> 00:25:06,080
Speaker 2: was investigating him.

511
00:25:06,400 --> 00:25:08,280
Speaker 1: So he was like, I'm just so over this. I'm

512
00:25:08,280 --> 00:25:08,960
Speaker 1: gonna yo yo.

513
00:25:09,240 --> 00:25:11,320
Speaker 2: Well, apparently the way I read it is that he

514
00:25:11,400 --> 00:25:14,280
Speaker 2: was trying to entertain lighting everything up. It's like here,

515
00:25:14,320 --> 00:25:16,520
Speaker 2: watch me yo yo And he was walking the dog.

516
00:25:16,400 --> 00:25:19,560
Speaker 1: And the who ax said no, wrap one.

517
00:25:19,720 --> 00:25:23,920
Speaker 2: So that's how yoyo's are connected to McCarthyism. If you

518
00:25:24,000 --> 00:25:26,200
Speaker 2: want to take a N S Y S K quizn

519
00:25:26,240 --> 00:25:26,679
Speaker 2: that comes up.

520
00:25:26,800 --> 00:25:29,480
Speaker 1: Plus yoyo's were huge back then. Totally thought that was

521
00:25:29,480 --> 00:25:30,960
Speaker 1: like the heyday. I think this is sixties.

522
00:25:31,160 --> 00:25:33,800
Speaker 2: Yeah, Nixon. Have you seen Nixon try to yo yo?

523
00:25:34,520 --> 00:25:34,600
Speaker 1: No?

524
00:25:34,760 --> 00:25:37,200
Speaker 2: Man, if you don't like Nixon, this will just make

525
00:25:37,240 --> 00:25:40,240
Speaker 2: you hate him even more. The night that they opened

526
00:25:40,240 --> 00:25:42,719
Speaker 2: the Grand Ole Opry and I think sometime in nineteen

527
00:25:42,760 --> 00:25:46,640
Speaker 2: seventy four, what's the main guy, like the whole cast

528
00:25:46,640 --> 00:25:50,200
Speaker 2: of hehaws behind Nixon and then the mate Roy Akeff. Yeah,

529
00:25:50,280 --> 00:25:52,760
Speaker 2: he presents Nixon with a yo yo and like has

530
00:25:52,800 --> 00:25:55,199
Speaker 2: to put it on Nixon's finger, and Nixon looks like

531
00:25:55,240 --> 00:25:58,240
Speaker 2: what's going on? You know? And and then he tries

532
00:25:58,280 --> 00:25:59,840
Speaker 2: to do it once and it just kind of like

533
00:26:00,040 --> 00:26:03,680
Speaker 2: flops down and makes like a sad trombone noise. Wow,

534
00:26:03,680 --> 00:26:06,040
Speaker 2: And he just has this sullen like look on his face,

535
00:26:06,080 --> 00:26:09,119
Speaker 2: like I don't like yo yo's. He looks kind of

536
00:26:09,160 --> 00:26:11,560
Speaker 2: like you did at the beginning of this episode.

537
00:26:11,920 --> 00:26:14,240
Speaker 1: Yeah, me and Tricky, Yeah you knew.

538
00:26:14,520 --> 00:26:17,560
Speaker 2: And then they took a yo yo in space Chuck, Yeah,

539
00:26:17,600 --> 00:26:18,280
Speaker 2: I saw that and.

540
00:26:18,240 --> 00:26:20,600
Speaker 1: It still worked.

541
00:26:21,160 --> 00:26:24,320
Speaker 2: It did work. They found that like letting it drop

542
00:26:24,400 --> 00:26:26,720
Speaker 2: did nothing because they were testing it in microgravity. But

543
00:26:26,760 --> 00:26:30,080
Speaker 2: if you throw it, it will it will go slowly.

544
00:26:30,320 --> 00:26:30,840
Speaker 1: You can do it.

545
00:26:31,119 --> 00:26:32,960
Speaker 2: You can do it slowly, but it will still spin

546
00:26:33,880 --> 00:26:37,840
Speaker 2: and it moves kind of just kind of gracefully along

547
00:26:37,960 --> 00:26:42,679
Speaker 2: the string like in just mid air, horizontally, and but

548
00:26:42,760 --> 00:26:43,639
Speaker 2: it'll never sleep.

549
00:26:44,280 --> 00:26:46,320
Speaker 1: Well, thank god NASA did that.

550
00:26:46,800 --> 00:26:48,600
Speaker 2: Yeah, back in nineteen eighty five.

551
00:26:48,640 --> 00:26:50,159
Speaker 1: Those are all the videos you see, though they do

552
00:26:50,359 --> 00:26:51,080
Speaker 1: much more than that.

553
00:26:51,080 --> 00:26:53,840
Speaker 2: That was back when NASA was like, we have so

554
00:26:53,960 --> 00:26:56,679
Speaker 2: much money, we don't know what to do. Let's launch

555
00:26:56,720 --> 00:26:59,960
Speaker 2: something and let's say the Toys in Space Project, right,

556
00:27:00,280 --> 00:27:00,800
Speaker 2: and they did.

557
00:27:00,920 --> 00:27:03,000
Speaker 1: Now this was just for Yoyo's. That was the only

558
00:27:03,040 --> 00:27:03,960
Speaker 1: thing they did on that flight.

559
00:27:04,119 --> 00:27:06,520
Speaker 2: Well, no, the Toys and Space Project in company or

560
00:27:06,680 --> 00:27:10,960
Speaker 2: encompassed sixty Shuttle missions, one for each toy that they

561
00:27:11,000 --> 00:27:14,280
Speaker 2: tested out. Wow, Jackson was one of the best ones.

562
00:27:15,280 --> 00:27:16,040
Speaker 1: The Bolo paddle.

563
00:27:16,240 --> 00:27:19,600
Speaker 2: Yeah, so that's uh, that's yo Yo's. Frankly, I'm pretty

564
00:27:19,600 --> 00:27:20,520
Speaker 2: happy with this one.

565
00:27:20,600 --> 00:27:22,240
Speaker 1: I thought you were going to lead in with something

566
00:27:22,280 --> 00:27:24,240
Speaker 1: on yo yo ma or something.

567
00:27:24,280 --> 00:27:26,800
Speaker 2: No, man, try to look up yoyo's in the news

568
00:27:26,840 --> 00:27:30,520
Speaker 2: and not get yo yo ma cheese. Can't do it, stupid.

569
00:27:31,160 --> 00:27:37,320
Speaker 2: I searched a yo yo minus ma minus knee, minus

570
00:27:37,359 --> 00:27:39,680
Speaker 2: gabba to finally get some stuff on.

571
00:27:39,760 --> 00:27:42,680
Speaker 1: O yo gabba gaba. Sure, ye oh what was the

572
00:27:42,720 --> 00:27:47,800
Speaker 1: other one yo mama neo yo MTV wraps that came

573
00:27:47,880 --> 00:27:48,600
Speaker 1: up too, did it?

574
00:27:48,880 --> 00:27:53,359
Speaker 2: Yeah? I stopped searching before I minused MTV too. You

575
00:27:53,400 --> 00:27:55,560
Speaker 2: know you could minus I was in the jew Yeah,

576
00:27:55,640 --> 00:27:58,119
Speaker 2: and it'll it'll root out all the search, all this,

577
00:27:58,440 --> 00:27:59,879
Speaker 2: all the results that have that.

578
00:28:00,119 --> 00:28:01,960
Speaker 1: Really, so you just put the minus.

579
00:28:01,720 --> 00:28:04,320
Speaker 2: Sign minus and then the next letter. No space, had

580
00:28:04,320 --> 00:28:06,600
Speaker 2: no idea, and you can do a bunch of different ones,

581
00:28:06,760 --> 00:28:10,080
Speaker 2: no comments, no nothing, just like minus gabba minus yo

582
00:28:10,640 --> 00:28:12,119
Speaker 2: minus mom, minus knee.

583
00:28:12,200 --> 00:28:18,080
Speaker 1: You literally just improved my life. Oh good, or my research.

584
00:28:18,000 --> 00:28:19,440
Speaker 2: For like that eight times a day?

585
00:28:19,640 --> 00:28:20,200
Speaker 1: Yeah?

586
00:28:20,280 --> 00:28:23,320
Speaker 2: All right, well that's it, all right, yo yosa. I

587
00:28:23,400 --> 00:28:25,720
Speaker 2: was in a jewelry store once and Neo came in.

588
00:28:26,200 --> 00:28:27,000
Speaker 2: It seemed nice.

589
00:28:27,560 --> 00:28:28,120
Speaker 1: Who's Neo?

590
00:28:28,680 --> 00:28:30,400
Speaker 2: He's this rapper He's from Atlanta.

591
00:28:30,640 --> 00:28:33,280
Speaker 1: I thought you were talking about the matrix. No, that's

592
00:28:33,320 --> 00:28:35,400
Speaker 1: like his real names Cana Neo.

593
00:28:35,640 --> 00:28:37,080
Speaker 2: This is ni Yo.

594
00:28:37,440 --> 00:28:39,160
Speaker 1: Oh yeah, I've heard of him.

595
00:28:39,280 --> 00:28:42,040
Speaker 2: Yeah him. Well, if you want to learn more about

596
00:28:42,120 --> 00:28:47,000
Speaker 2: Yoyo's including some really top notch illustrations, this is one

597
00:28:47,000 --> 00:28:49,360
Speaker 2: of those ones that you will see why we have

598
00:28:49,720 --> 00:28:52,840
Speaker 2: staff illustrators here at in color.

599
00:28:52,920 --> 00:28:52,960
Speaker 1: No.

600
00:28:53,040 --> 00:28:55,800
Speaker 2: Yes, I saw you want to type in yo Yo

601
00:28:56,040 --> 00:28:57,920
Speaker 2: at the in the handy search bar at house stuff

602
00:28:57,920 --> 00:29:00,000
Speaker 2: works dot com. That'll bring up that really cool article.

603
00:29:00,800 --> 00:29:03,840
Speaker 2: And I said handy search bar. So now it's time

604
00:29:03,840 --> 00:29:07,520
Speaker 2: for Chuck to shine with another edition of Listener Mail.

605
00:29:10,120 --> 00:29:14,400
Speaker 1: Josh, this is one of our oldest than not by age,

606
00:29:14,560 --> 00:29:18,160
Speaker 1: but one of our most loyal fans, Anna Spies. She

607
00:29:18,280 --> 00:29:21,000
Speaker 1: has a band and they put together Well, let me

608
00:29:21,040 --> 00:29:23,360
Speaker 1: just read it. This is coming out shortly after Christmas,

609
00:29:23,400 --> 00:29:26,880
Speaker 1: and she said it was still great to read this. Hi,

610
00:29:26,960 --> 00:29:30,560
Speaker 1: guys and Jerry. Since we're firmly in the festive, greedy

611
00:29:30,600 --> 00:29:33,160
Speaker 1: little grip of the holiday season, I was wondering if

612
00:29:33,200 --> 00:29:34,800
Speaker 1: you could give a shout out to a project I'm

613
00:29:34,800 --> 00:29:37,280
Speaker 1: involved in or my band is. At least it's a

614
00:29:37,360 --> 00:29:40,280
Speaker 1: charity album to raise funds for the continued fallout from

615
00:29:40,320 --> 00:29:43,520
Speaker 1: the Japanese earthquake and nuclear disaster, and the light of

616
00:29:43,560 --> 00:29:45,960
Speaker 1: everything that's happened since, I know, it's been put on

617
00:29:45,960 --> 00:29:49,360
Speaker 1: the back burner of most people's charitable contributions, which is

618
00:29:49,360 --> 00:29:52,080
Speaker 1: why we were thrilled and honor to our part to

619
00:29:52,360 --> 00:29:56,560
Speaker 1: re raise awareness when the label releasing this compilation approached

620
00:29:56,640 --> 00:29:59,280
Speaker 1: us to contribute a track. So you know, she's right

621
00:30:00,120 --> 00:30:02,560
Speaker 1: about these tragedies that happen and then six months later

622
00:30:02,560 --> 00:30:03,640
Speaker 1: you kind of forget about it.

623
00:30:03,640 --> 00:30:06,680
Speaker 2: It's the curse of the news cycle exactly.

624
00:30:06,760 --> 00:30:09,800
Speaker 1: But luckily there's a lot of people that my friend

625
00:30:09,880 --> 00:30:11,680
Speaker 1: Dave is one of them that's still working, like on

626
00:30:11,720 --> 00:30:14,840
Speaker 1: the tsunami from five or six years ago. Oh that's great,

627
00:30:14,960 --> 00:30:19,120
Speaker 1: so continued help is always needed. There's a CD that's

628
00:30:19,160 --> 00:30:22,120
