WEBVTT - How Board Breaking Works 0:00:01.120 --> 0:00:04.560 Welcome to Stuff you should know from how Stuff Works 0:00:04.600 --> 0:00:13.880 dot com. Hey, and welcome to the podcast. I'm Josh Clark, 0:00:14.000 --> 0:00:17.439 There's Charles W Chuck Bryant, and there's Jerry over there. 0:00:18.000 --> 0:00:22.000 And this is stuff you should know all about Mars. 0:00:22.800 --> 0:00:27.080 Oh wait, I mean it's all about board breaking, that's right, 0:00:27.960 --> 0:00:31.080 board breaking. I gotta keep them straight. Do you want 0:00:31.080 --> 0:00:38.600 to explain what you just said? Sure? So. Um, you know, 0:00:38.720 --> 0:00:41.760 when we pick our topics, one of us will send 0:00:41.760 --> 0:00:43.800 a topic, the other one will send a different topic. 0:00:43.880 --> 0:00:45.720 Then we go off and do our research, and then 0:00:45.760 --> 0:00:47.800 we come back together and record it. That's the stuff 0:00:47.800 --> 0:00:52.120 you should know, way right, that's the way. Um. I 0:00:52.159 --> 0:00:54.240 want to preface this by saying we have more than 0:00:54.280 --> 0:00:57.480 a thousand episodes that we've done. Okay, to bear that 0:00:57.560 --> 0:01:02.080 mind everybody, more than I say you, How Mars Works 0:01:02.280 --> 0:01:05.360 was my pick for this week, and uh, I went 0:01:05.400 --> 0:01:08.000 about and started studying. I think you did some studying 0:01:08.000 --> 0:01:11.200 as well. And then I got an email from you 0:01:11.400 --> 0:01:14.680 this morning, early this morning saying, um, we've already done 0:01:14.720 --> 0:01:20.640 how Mars Works. Hours of Mars research just totally wasted. 0:01:20.920 --> 0:01:22.960 I know so much. I know so much about Mars 0:01:23.080 --> 0:01:24.640 right now that it's never No one's ever going to 0:01:24.760 --> 0:01:28.399 hear it. I'm going to take it to my grave. Yeah. 0:01:28.520 --> 0:01:31.560 So we swapped it out instead with how board breaking works, 0:01:31.600 --> 0:01:34.839 which is fascinating if you ask me. Yeah, man, good 0:01:34.880 --> 0:01:38.440 find Yeah I thought so too. I believe we covered 0:01:38.880 --> 0:01:44.200 cart before. Who knows, Chuck? Who has any idea? Well, 0:01:44.319 --> 0:01:48.360 Jill Hurley knows. Yes, Jill Hurley, our minister of status, 0:01:48.440 --> 0:01:50.440 usually keeps track of this stuff. But she does. We 0:01:50.480 --> 0:01:52.600 should just start emailing her every time we have an 0:01:52.640 --> 0:01:55.720 idea instead instead of looking at the spreadsheet that she 0:01:55.800 --> 0:02:00.480 sends us exactly like a couple of dopes. Yeah. No, 0:02:00.680 --> 0:02:06.400 but board breaking I'm a sure we did not do before. No, uh, 0:02:06.400 --> 0:02:08.600 And we might as well go ahead and do a 0:02:08.600 --> 0:02:11.800 couple of things. First of all, c o A and say, 0:02:12.040 --> 0:02:16.320 do not try to break boards or anything with your 0:02:16.360 --> 0:02:20.480 hands and feet unless you were trained to do so. Yes, 0:02:21.440 --> 0:02:25.240 don't get inspired by this show. If you are inspired, 0:02:25.360 --> 0:02:28.560 be inspired to go take up martial arts because from all, 0:02:28.680 --> 0:02:32.880 from everything I can find, it's a really great um 0:02:33.760 --> 0:02:36.919 thing to get into martial arts. Yeah, it is. It 0:02:36.919 --> 0:02:39.960 teaches you focus and discipline and training and strength and 0:02:40.000 --> 0:02:43.600 self confidence and actually, like the injury rate is really 0:02:43.639 --> 0:02:46.680 really low, way lower than you would think. Um, so 0:02:46.720 --> 0:02:49.720 it's actually pretty good sport to get into. Yeah. And 0:02:49.760 --> 0:02:52.480 the other thing to point out early on is, uh, 0:02:52.840 --> 0:02:57.639 it is not just boards, but concrete blocks and glass 0:02:57.880 --> 0:03:01.320 and ice and what else. Glass I think is much 0:03:01.360 --> 0:03:05.000 more just for looks. Yeah. There's this one guy who 0:03:05.080 --> 0:03:07.240 who I found because I was kind of looking up 0:03:07.320 --> 0:03:09.400 records and things, and I'll get to that later, but 0:03:10.040 --> 0:03:11.840 I can't remember his name, but he seems to make 0:03:11.880 --> 0:03:15.680 a big show about chopping through a bunch of glass. 0:03:16.560 --> 0:03:20.520 If he could punch a hole clear through some glass 0:03:20.560 --> 0:03:25.200 without breaking the glass fish shape hole like a cartoon Yeah, 0:03:25.240 --> 0:03:27.600 like a bullet hole, but with a fist. Now, that 0:03:27.639 --> 0:03:30.600 would be super impressive breaking a bunch of glass. I mean, 0:03:31.320 --> 0:03:34.600 that's that's not hard, And we'll find out why it's 0:03:34.600 --> 0:03:37.320 not hard later on, because we're going to talk about 0:03:37.320 --> 0:03:39.800 the physics of this chuck, which I'm a little psyched about. Yeah. 0:03:39.800 --> 0:03:42.080 And another thing that I didn't see in my research 0:03:42.160 --> 0:03:44.600 that I always heard, which maybe a wives tale, is 0:03:44.640 --> 0:03:47.120 that when they do the thing where they stack a 0:03:47.120 --> 0:03:50.040 bunch of boards, that like you're really just breaking the 0:03:50.080 --> 0:03:53.560 first board and then the other boards break the other boards. 0:03:54.120 --> 0:03:57.160 Is that true? Yeah? Yeah, so that was something that 0:03:57.200 --> 0:04:00.640 I came across this. So board breaking, at least in 0:04:00.720 --> 0:04:07.960 Japan is called tamashawari. And there's fake tami shiwari, which 0:04:08.040 --> 0:04:12.880 is probably of the tamashwari out there, and then there's 0:04:12.880 --> 0:04:16.520 actual real tamashwari, which you have to be basically insane 0:04:16.520 --> 0:04:20.800 to try, even as like a black belt um karate person. 0:04:20.839 --> 0:04:24.560 But what do you mean by fake if instead of fake, 0:04:24.640 --> 0:04:28.680 we'll call it physics assisted, Okay, Whereas with like that, 0:04:28.960 --> 0:04:33.400 that one percent of tamashawari, it's it is what it 0:04:33.400 --> 0:04:35.880 it appears to be. You're you're really punching through like 0:04:35.920 --> 0:04:39.480 a big thick piece of wood or something like that. Well, 0:04:39.600 --> 0:04:41.880 I think I would love to cover the very beginnings 0:04:41.880 --> 0:04:43.720 of this article though, because I thought I had never 0:04:43.760 --> 0:04:48.040 heard that story about the the legend of the origins 0:04:48.120 --> 0:04:51.800 of pin Jack's a lot take us the story Bill Chuck. 0:04:52.600 --> 0:04:58.839 So there's an island called uh bawean Uh in ancient Indonesia, 0:04:59.200 --> 0:05:02.680 and this is main mainly legend, but who knows it 0:05:02.960 --> 0:05:05.600 might have come down like this, But supposedly there was 0:05:05.640 --> 0:05:09.159 a lady there named Rama Sukana, who was washing her 0:05:09.200 --> 0:05:12.719 close in the river, looked up saw some monkeys fighting 0:05:12.880 --> 0:05:16.839 in the trees and really sort of got into studying 0:05:16.880 --> 0:05:20.960 them and how they fought each other. Started practicing that 0:05:21.040 --> 0:05:25.080 out by the river banks. Took so much time. She 0:05:25.200 --> 0:05:27.599 came home and her husband was ticked off and was like, 0:05:27.600 --> 0:05:31.480 where's my dinner? And because this is ancient times, it's 0:05:31.520 --> 0:05:35.680 fully okay for me to two abuse you because my 0:05:35.720 --> 0:05:38.200 dinner is not on the table. And she was like, 0:05:38.279 --> 0:05:40.320 oh no, no, no, I now know the way of 0:05:40.320 --> 0:05:44.600 the monkey. And she she fought him back and it worked, 0:05:45.560 --> 0:05:47.520 and it kept working. He kept coming at her and 0:05:47.560 --> 0:05:52.360 she kept just going kabat foot and oh ah, right, 0:05:52.920 --> 0:05:55.480 and she kept putting him on his butt so much 0:05:55.560 --> 0:06:01.880 so that he said, master trained me. Yeah. See that's 0:06:01.920 --> 0:06:04.600 where the story loses me, where he's just he gives 0:06:04.640 --> 0:06:06.560 up and says, you're pretty good at this. I gotta admit, 0:06:07.480 --> 0:06:09.400 what do you say you teach the old man? Right? 0:06:10.120 --> 0:06:12.440 I think that's uh, that's what they call when you 0:06:12.440 --> 0:06:15.480 can't beat them, join them. Yeah, but it's a good story. 0:06:15.800 --> 0:06:19.520 And as the origins of the Indonesian martial art, pent 0:06:19.839 --> 0:06:23.520 jacks a lot, yeah, which I thought that was very 0:06:23.600 --> 0:06:26.640 very odd that this was included in this article because 0:06:26.680 --> 0:06:29.320 I looked up pen jack, so pen Jack's a lot, 0:06:30.040 --> 0:06:32.839 and it looked like it was very much into fighting 0:06:32.880 --> 0:06:36.320 with knives and spears, way more than breaking boards are 0:06:36.400 --> 0:06:39.719 using open handed stuff, and that's no monkey stuff. No, 0:06:40.400 --> 0:06:44.279 but I think it is based on strikes in the 0:06:44.320 --> 0:06:47.440 animal kingdom, not just monkeys, but like cobra strikes and 0:06:47.440 --> 0:06:50.719 and using like those kind of like approaches, but rather 0:06:50.760 --> 0:06:53.039 than with your empty hand, it's you're using knives. So 0:06:53.080 --> 0:06:56.920 I don't know why that was included instead. Karate um 0:06:57.160 --> 0:07:00.520 is much more associated with board breaking. Again, there's a 0:07:00.600 --> 0:07:04.520 Japanese word for board breaking, tami shawari. Yeah, and did 0:07:04.520 --> 0:07:07.719 you know that cobra kai actually means knife wielding cobra? 0:07:08.680 --> 0:07:12.560 Does it really? Yeah? Well, I mean it could. It 0:07:12.560 --> 0:07:15.000 could be like cobra and knife, and you could just 0:07:15.120 --> 0:07:17.760 interpret it his knife wheeling cobra rather than a knife 0:07:17.760 --> 0:07:19.880 made out of a cobra. Could you imagine anything more 0:07:19.960 --> 0:07:23.880 terrifying than a cobra holding a knife? No? No, maybe 0:07:24.480 --> 0:07:31.480 a deranged karate monkey with the cobra wielding and knife, 0:07:31.720 --> 0:07:37.000 or an alligator with an assault rifle. Yeah, that's pretty scary, 0:07:37.000 --> 0:07:41.920 pretty scary. So karate is meant to be done with 0:07:41.960 --> 0:07:45.720 open hand. It actually means open hand, empty hand, right, yeah, 0:07:45.880 --> 0:07:49.760 one of the two. Yeah, And the origins of karate 0:07:49.840 --> 0:07:52.600 apparently came from when the peasantry was stripped of their 0:07:52.640 --> 0:07:56.280 weapons in the sixteenth and seventeenth century because the Japanese government, 0:07:56.680 --> 0:08:00.160 feudal government, said, we're worried you guys don't don't really 0:08:00.240 --> 0:08:02.880 like our policies as much as you pretend to, and 0:08:02.920 --> 0:08:04.840 we're afraid you're gonna rebel, so we're gonna take all 0:08:04.880 --> 0:08:10.520 your weapons. So they developed a empty hand technique for fighting, 0:08:10.560 --> 0:08:15.000 which was karate, and again part of karate. Over the years, 0:08:15.040 --> 0:08:19.400 I'm not exactly sure where temi shawari originator when I 0:08:19.400 --> 0:08:23.520 should say, but over the years, the idea of breaking 0:08:23.560 --> 0:08:27.920 boards is a demonstration of skill and training and focus 0:08:27.960 --> 0:08:31.520 and strength um has developed to where now to me 0:08:31.600 --> 0:08:35.720 it's basically synonymous with martial arts. Yeah, breaking some boards, 0:08:38.360 --> 0:08:40.160 uh yeah, and they had in here. I'm not so 0:08:40.200 --> 0:08:43.160 sure this is right that they turned to breaking boards 0:08:43.240 --> 0:08:46.120 because hitting people wasn't a thing that you should do. 0:08:46.760 --> 0:08:48.880 But I don't think that's quite right, is it. I'm 0:08:48.920 --> 0:08:50.760 not sure, Man, I really am not sure that's what 0:08:50.800 --> 0:08:54.240 I'm saying, Like the origin of it, no idea. I 0:08:54.280 --> 0:08:57.640 did see that there's um, you know, it's been around 0:08:57.640 --> 0:09:00.880 for a little while, and there are some customary and 0:09:00.920 --> 0:09:04.480 traditional like um things with the board, like for example, 0:09:04.520 --> 0:09:07.560 you're supposed to use cedar specific type of cedar or 0:09:07.600 --> 0:09:09.880 drake um, and there's things like that. But no, I 0:09:09.880 --> 0:09:12.439 didn't see where it came from or exactly why other 0:09:12.480 --> 0:09:15.760 than somebody. Maybe somebody was punching through a door and 0:09:16.280 --> 0:09:19.560 that looked pretty cool, and so they started punching through doors, 0:09:19.559 --> 0:09:21.760 and then the doors got smaller, and then you have 0:09:21.920 --> 0:09:25.960 Tamashawari board breaking. Well, what we do know that there 0:09:26.040 --> 0:09:31.720 is a human instinct to not punch something uh with 0:09:31.800 --> 0:09:36.040 no give, Like there is an ingrained instinct to pull 0:09:36.120 --> 0:09:38.640 back when you go to hit a wall or to 0:09:38.720 --> 0:09:43.160 punch a board or something like that, or a person even. Yeah, 0:09:43.240 --> 0:09:45.280 and we'll talk a little bit more about that in 0:09:45.280 --> 0:09:48.120 a few minutes. But I thought this is really interesting 0:09:48.160 --> 0:09:52.040 this other article you sent just about how strong bones 0:09:52.080 --> 0:09:55.679 are and kind of what happens when you hit another person. Yeah, 0:09:55.720 --> 0:09:57.920 So I mean, if you stop and think about it 0:09:57.960 --> 0:10:01.040 breaking through a board, it looks awesome because it is 0:10:01.040 --> 0:10:05.840 pretty impressive. But your your bone and your hand and 0:10:05.880 --> 0:10:09.360 your foot and your leg are actually way more impressive 0:10:09.400 --> 0:10:14.000 than would because they are capable of doing some amazing stuff. 0:10:14.200 --> 0:10:16.880 And if you stop and think about it, your bone 0:10:17.520 --> 0:10:21.400 is capable of withstanding tremendous amounts of pressure and force. 0:10:22.160 --> 0:10:24.200 But at the same time, you can use that bone 0:10:24.240 --> 0:10:29.920 to break another bone, which is kind of paradoxical, you know. Yeah, 0:10:30.120 --> 0:10:34.000 but it's pretty neat. So yeah, there's there's if you 0:10:34.040 --> 0:10:36.640 look at bone, there's a lot of stress you can 0:10:36.720 --> 0:10:39.880 put it on before it's going to break. Yeah, so, 0:10:40.360 --> 0:10:44.520 uh a cubic inch of bone. And they point out 0:10:44.600 --> 0:10:47.520 this article in principle, I'm sure there are, you know, 0:10:47.800 --> 0:10:53.400 people like Samuel Jackson an Unbreakable Mr Glass, Sure he 0:10:53.440 --> 0:10:57.160 had a physical condition. I think they're doing another movie 0:10:57.200 --> 0:11:01.400 of of him and the guy from uh, what was 0:11:01.440 --> 0:11:05.040 the most recent one that Split? Split. Yeah, they're doing 0:11:05.080 --> 0:11:09.480 like basically a sequel to Split featuring Mr Glass and 0:11:09.880 --> 0:11:12.720 Bruce Willis. It's all, oh, wow, that's gonna be good. 0:11:12.840 --> 0:11:15.000 It looks pretty good to me so far. I went 0:11:15.040 --> 0:11:18.240 back and rewatched Unbreakable, and I was like, this is 0:11:18.320 --> 0:11:20.320 much better than I thought it was the first time. 0:11:20.360 --> 0:11:23.959 It's a good movie. I totally agree. I think people 0:11:24.040 --> 0:11:26.400 expected well, I think it it got it to do 0:11:26.480 --> 0:11:29.400 at the time, but it was a movie about the 0:11:29.440 --> 0:11:33.160 beginnings of a It was just an ultralong origin story, right, 0:11:33.520 --> 0:11:36.040 which you didn't realize until about two thirds of the 0:11:36.080 --> 0:11:38.040 way through, you know, and then you really got it 0:11:38.120 --> 0:11:40.319 at the end. But yeah, I think everybody was expecting, 0:11:40.480 --> 0:11:43.440 give me another sixth sense, baby, kind of need that jolt, 0:11:44.160 --> 0:11:46.680 and uh, he just never delivered like he did on 0:11:46.720 --> 0:11:48.560 the sixth sense. So he's kind of cursed by it, 0:11:48.760 --> 0:11:50.440 which is why you have to go back years later 0:11:50.440 --> 0:11:53.160 and see it again. You're like, oh, now that I'm 0:11:53.200 --> 0:11:56.920 out of like the six cents junkiness, I I can 0:11:56.960 --> 0:12:00.079 appreciate Unbreakable and the Village too. I saw that in 0:12:00.200 --> 0:12:02.120 le two and I'm like, this is better than I 0:12:02.160 --> 0:12:04.800 thought it was. Yeah. That was Manky's pick on movie Crush. 0:12:05.280 --> 0:12:09.079 Oh that's right, yeah, yeah, that was yes, totally kind 0:12:09.080 --> 0:12:13.080 of on the nose for Airmankey. Yeah. Um, all right, 0:12:13.160 --> 0:12:16.520 So Mr glass aside, though, in principle, a bone can 0:12:16.640 --> 0:12:21.040 bear a load of nineteen thousand pounds or more, and 0:12:21.240 --> 0:12:25.040 that makes it as your correct article said four times 0:12:25.040 --> 0:12:28.800 as strong as concrete, whereas R said forty times. Yeah, 0:12:28.920 --> 0:12:33.000 who cares, which is not correct. Right, So this this 0:12:33.040 --> 0:12:35.400 is I think a Live science article I found this in. 0:12:35.520 --> 0:12:41.880 But if you balanced five American pickup trucks, says standard 0:12:41.880 --> 0:12:46.880 pickup truck. So I'm just gonna go with a one fifty. Yeah. 0:12:47.080 --> 0:12:49.720 Well I wasn't gonna say for it. I was just 0:12:49.920 --> 0:12:51.439 you know, if you were in the know, I was 0:12:51.480 --> 0:12:53.400 just going to leave it at that. But if you 0:12:53.480 --> 0:12:59.319 balance five Ford f one fifties nose to tail um 0:12:59.440 --> 0:13:04.040 on top of your armbone, theoretically it should be able 0:13:04.080 --> 0:13:07.079 to hold that up. You would wish that you were dead, 0:13:07.720 --> 0:13:10.599 but your armbone would just be like, oh god, this 0:13:10.880 --> 0:13:13.800 I'm not gonna break, and it might not break. But 0:13:14.080 --> 0:13:17.160 again the point is this. That is the amount of 0:13:17.320 --> 0:13:21.880 actual weight, but weight can actually be combined in other 0:13:21.920 --> 0:13:25.199 ways and delivered an other way. So if you delivered 0:13:25.400 --> 0:13:28.960 far far less than that with um a lot more 0:13:29.080 --> 0:13:33.719 velocity um, your your bone would just snap right in two. 0:13:34.120 --> 0:13:37.200 So there's a lot of variables they're including not just 0:13:37.520 --> 0:13:40.480 how that amount of weight is delivered in what what 0:13:40.600 --> 0:13:44.960 kind of force, but also your age, your health. There's 0:13:45.000 --> 0:13:48.000 a lot of stuff, but like you said, generally speaking, 0:13:48.360 --> 0:13:51.320 your bone, a cubic inch of bone could bear nine 0:13:52.000 --> 0:13:56.840 pounds or about eight thousand, six hundreds of weight. Yeah. 0:13:56.960 --> 0:13:59.160 And although this is gets away from board breaking, it 0:13:59.240 --> 0:14:00.640 was in the article sent and I thought it was 0:14:00.679 --> 0:14:03.680 super interesting. When it comes to getting in a fistfight 0:14:03.840 --> 0:14:07.960 or boxing. When someone gets knocked out by a punch, 0:14:08.760 --> 0:14:12.120 it's not necessarily because they get hit so hard in 0:14:12.160 --> 0:14:15.880 the head. It's that there if you hit someone in 0:14:15.800 --> 0:14:17.959 the cheek, you know, right there, and the and the 0:14:18.040 --> 0:14:22.320 kisser and the jaw, it's the head spin that does it. 0:14:22.560 --> 0:14:27.040 So if your head spins around, uh from zero to 0:14:27.120 --> 0:14:33.040 forty three RPMs in a second, your your head stresses 0:14:33.080 --> 0:14:37.800 out and the brain shuts down as a protection. Yeah, 0:14:37.880 --> 0:14:42.960 I had no idea of getting knocked out chance if 0:14:43.000 --> 0:14:47.320 it's up to RPMs. So that's why boxers built up 0:14:47.320 --> 0:14:50.040 their neck muscles so their head doesn't snap to the 0:14:50.080 --> 0:14:53.160 side as much. Yeah, totally had no idea about any 0:14:53.240 --> 0:14:55.880 of that, or getting hit in the stomach, Like when 0:14:55.880 --> 0:14:58.680 the wind is knocked out of you, that's a spasm 0:14:58.720 --> 0:15:02.760 of your diaphragm right right. And the reason why you 0:15:02.800 --> 0:15:05.760 can make somebody's head spin like that, or make or 0:15:06.040 --> 0:15:09.600 cause somebody's diaphragm to spas them is because you're concentrating 0:15:09.880 --> 0:15:12.760 a tremendous amount of force in a fairly small area. 0:15:13.120 --> 0:15:15.200 Like if you look at the front if you make 0:15:15.240 --> 0:15:17.560 a fist and then look at the front of your 0:15:17.600 --> 0:15:21.800 fingers where the fist makes contact with whatever that's that's 0:15:21.840 --> 0:15:25.280 actually a relatively small area that you're putting a tremendous 0:15:25.280 --> 0:15:30.880 amount of mass and velocity behind. And you combine those two, 0:15:30.880 --> 0:15:34.080 you multiply those two, and you have force. And humans 0:15:34.120 --> 0:15:37.800 can can concentrate a pretty pretty significant amount of force. 0:15:37.920 --> 0:15:42.160 This Life Science article found that a professional boxer could 0:15:42.160 --> 0:15:45.960 generate about five thousand Newton's of force, and a Newton, 0:15:46.000 --> 0:15:48.480 by the way, is the amount of force it takes 0:15:48.520 --> 0:15:53.200 to move one kilogram one meter, which makes me want 0:15:53.240 --> 0:15:55.840 to go move a kilogram a meter so bad just 0:15:55.880 --> 0:15:58.080 to be like, I just used a Newton. I just 0:15:58.160 --> 0:16:01.840 exerted a Newton right there? You know? Is that just 0:16:01.920 --> 0:16:06.720 me that you don't want to do that too? So um. 0:16:06.760 --> 0:16:09.720 A boxer can generate about five thousand Newton's of force 0:16:09.760 --> 0:16:13.440 with a punch, which is about half of a ton 0:16:14.280 --> 0:16:20.640 of um of force exerted on the Earth's surface. Okay, 0:16:21.120 --> 0:16:23.480 half a ton of force in your little your little 0:16:23.520 --> 0:16:28.640 fist right there. And because four sequels mass times velocity, 0:16:29.000 --> 0:16:34.480 if you can generate more um velocity and you and 0:16:34.600 --> 0:16:38.240 you can use more mass, you can generate more force. 0:16:38.280 --> 0:16:41.120 And we'll talk more about that later on with the physics. 0:16:41.160 --> 0:16:43.960 But that's just a little teaser. Yeah, And this is 0:16:44.000 --> 0:16:45.800 also the point, and I've pointed this out before, I 0:16:45.840 --> 0:16:48.640 believe where I would like to say that I am 0:16:48.960 --> 0:16:52.760 forty seven years old and I have never punched or 0:16:52.840 --> 0:16:56.160 hit anyone in my life. Nor been punched or hit. 0:16:56.640 --> 0:16:59.040 That's great, man, never been in a fight. I kind 0:16:59.080 --> 0:17:01.200 of feel like I should get in a fight. I 0:17:01.280 --> 0:17:03.400 don't think so. I think you should feel the opposite 0:17:03.400 --> 0:17:06.119 of that. You should be proud of it. Yeah, just 0:17:06.160 --> 0:17:07.800 be like, I've never been in a fight. I'm gonna 0:17:07.840 --> 0:17:11.119 die having never been in a fist fight. You definitely 0:17:11.160 --> 0:17:14.480 don't need to. Don't listen to fight Club. It was 0:17:14.560 --> 0:17:17.320 made up, by the way. All right, should we take 0:17:17.320 --> 0:17:19.240 a break, Yeah, all right, We'll take a break and 0:17:19.320 --> 0:17:22.280 we'll talk more about board board breaking right after this, 0:17:40.960 --> 0:17:46.840 all right, Chuck so um when you actually break aboard, 0:17:47.440 --> 0:17:49.440 we can tell you how to do that. But again 0:17:49.480 --> 0:17:52.480 I want to preface it with like, just don't don't 0:17:52.560 --> 0:17:54.679 go do this, don't listen to us and do this. Like, 0:17:54.720 --> 0:17:57.320 if you want to do this, go check out martial arts, 0:17:57.320 --> 0:18:00.520 go to your nearest O Joe and see what's going down. 0:18:00.720 --> 0:18:04.639 That's right, But just for the sake of sharing information, 0:18:04.800 --> 0:18:09.440 that's what we're doing here. Okay. Yes, So if you 0:18:10.000 --> 0:18:12.919 if you watch somebody break aboard, you're gonna see that 0:18:12.960 --> 0:18:17.280 there's actually like a fairly uniform shape to them. They're 0:18:17.359 --> 0:18:22.720 usually about a foot wide, they're usually kind of squarish, 0:18:22.800 --> 0:18:26.680 and there's something like about three quarters of an inch thick. 0:18:27.160 --> 0:18:30.760 And again, like I said, traditionally, um, the wood is 0:18:30.760 --> 0:18:33.399 supposed to be cedar, but I think these days most people, 0:18:33.800 --> 0:18:36.560 uh say pine. They use pine because it's a soft 0:18:36.600 --> 0:18:40.080 wood and it breaks easier than a hardwood like oak 0:18:40.200 --> 0:18:44.199 or something like that. Yeah, And they also suggest to 0:18:44.359 --> 0:18:46.919 not have like a big not right in the center 0:18:47.040 --> 0:18:49.680 of this board or hopefully anywhere on the board, but 0:18:49.720 --> 0:18:53.240 definitely not where you're punching, because the center is where 0:18:53.240 --> 0:18:55.720 you want to be punching. And this is usually either 0:18:55.880 --> 0:18:59.920 held by somebody or you see them set up sometimes 0:19:00.040 --> 0:19:04.200 with on on stands and stuff being held. Yeah, if 0:19:04.240 --> 0:19:08.000 you watch Karate Kid too, when daniels Son breaks through 0:19:08.280 --> 0:19:11.480 those six sheets of ice, I don't remember that at all. 0:19:11.800 --> 0:19:14.040 They have It was like in a bar. He took 0:19:14.080 --> 0:19:17.720 a bet Actually, Mr Miyagi kind of forced him to 0:19:17.720 --> 0:19:21.960 take the bet um because he was being betted against 0:19:22.000 --> 0:19:27.280 by Mr Miyagi's rivals. Nephew, Okay, he's got to see it, 0:19:27.560 --> 0:19:29.359 but he got a good memory of Karate Kid too. 0:19:29.600 --> 0:19:33.800 I just watched it like an hour ago, okay, but yeah, 0:19:33.920 --> 0:19:36.520 they had like a stand that they put these sheets 0:19:36.520 --> 0:19:39.480 of ice in. It was pretty awesome, pretty cool little gizmo. 0:19:39.640 --> 0:19:41.800 I don't think there's any reason to make it unless 0:19:41.840 --> 0:19:43.920 you do kind of have a bar where people break 0:19:43.960 --> 0:19:46.760 ice and stuff. But it's uh, I just thought it 0:19:46.760 --> 0:19:48.800 was pretty cool. But for the most part, you see 0:19:48.840 --> 0:19:51.280 somebody just standing there holding it like it's like a 0:19:51.280 --> 0:19:54.359 punching target or something. Yeah, and there's I mean, it 0:19:54.400 --> 0:19:56.879 kind of depends, that's if you're punching straight through with 0:19:56.920 --> 0:20:01.639 your knuckles. You've also seen things stacked like spread between 0:20:01.680 --> 0:20:04.320 two bricks, a bunch of wood stacked and you can 0:20:04.800 --> 0:20:07.440 use a few techniques here at the hammer fist, which 0:20:07.520 --> 0:20:09.560 is like if you were just pounding on a you know, 0:20:10.080 --> 0:20:14.320 on a table with your with your hand like hulk smash, yeah, 0:20:14.359 --> 0:20:17.840 hulk smash or what's known as palm heel. And that's 0:20:17.840 --> 0:20:21.439 when you yeah, with with your palm. Yeah. If I 0:20:21.480 --> 0:20:23.439 saw somebody break a board like that, I would be 0:20:23.480 --> 0:20:26.840 truly impressed that I have not seen. Have you seen 0:20:26.880 --> 0:20:30.800 somebody break a board in real life? No? Not not 0:20:30.960 --> 0:20:33.840 in person? No I haven't either. Uh. And then the 0:20:33.880 --> 0:20:39.399 old knife hand, which is the classic karate chop. The 0:20:39.480 --> 0:20:41.080 reason why you want to hit the center of the 0:20:41.119 --> 0:20:45.360 board is myriad number one. That's where the least amount 0:20:45.480 --> 0:20:49.760 of strength is in the board. It's not around the edges, 0:20:49.800 --> 0:20:54.119 it's more in the center. And depending on how you're hitting, 0:20:54.200 --> 0:20:56.680 let's let's just go with the good old fashioned karate chop. 0:20:56.920 --> 0:20:59.560 What's that one called the knife hand? Yeah, and when 0:20:59.600 --> 0:21:02.000 you can all so do this these these uh with 0:21:02.119 --> 0:21:06.320 kicks you can which to me it just seems terribly scary. 0:21:06.560 --> 0:21:08.960 I don't know about you, but like I don't want 0:21:09.000 --> 0:21:12.439 anything to happen to my ankle or my heel or 0:21:12.480 --> 0:21:16.000 my achilles heel. Or any my toes. Nothing like that. 0:21:16.520 --> 0:21:20.639 Like the the punching breaking with your hands or fists, 0:21:20.640 --> 0:21:23.719 that's that's cool enough, But like your foot, I'd be 0:21:23.840 --> 0:21:26.159 very It would take a tremendous amount of training for 0:21:26.200 --> 0:21:28.360 me to get to that point. All right. So we're 0:21:28.400 --> 0:21:31.320 going with the standard karate chop, right, And when you're 0:21:31.560 --> 0:21:33.600 doing the standardkarate chop, so the board is going to 0:21:33.680 --> 0:21:37.840 be flat relative to the earth, and you are going 0:21:37.920 --> 0:21:42.440 to bring your fist down or your your karate chop 0:21:42.520 --> 0:21:46.240 down going with the grain, you will have a tremendously 0:21:46.320 --> 0:21:50.040 difficult time breaking the board against the grain. You want 0:21:50.040 --> 0:21:53.560 to go bring the line of your hand parallel with 0:21:53.680 --> 0:21:57.600 the grain. Yeah, I didn't fully get that, Okay. So 0:21:58.040 --> 0:21:59.879 if you have a flat board in front of you, 0:22:00.000 --> 0:22:02.199 you're you're on your knees and you're like about to 0:22:02.280 --> 0:22:05.399 chop it, and you hold your hold your fist up 0:22:05.440 --> 0:22:07.320 like that, or hold your karate chop up like this 0:22:07.760 --> 0:22:10.160 right in front of you, and you start to bring 0:22:10.200 --> 0:22:14.840 it down. The grain of the wood should be going 0:22:15.080 --> 0:22:18.960 the same direction as your hand. But what I mean 0:22:19.000 --> 0:22:20.960 that makes sense if your hand is in karate chop 0:22:21.000 --> 0:22:23.320 mode because there's a clear line. But what about when 0:22:23.320 --> 0:22:27.800 it's a fist. I don't know. Maybe it matters less 0:22:27.800 --> 0:22:31.520 because it's a fist. I could see it mattering more 0:22:31.560 --> 0:22:34.880 because there's so much less surface area that's making contact 0:22:34.960 --> 0:22:37.320 with the karate chop than like with the whole fist. 0:22:37.400 --> 0:22:39.960 So I would guess the grain definitely would matter more 0:22:40.040 --> 0:22:43.720 with that, al Right, But regardless supposedly they say going 0:22:43.760 --> 0:22:47.080 with the grain is easier, Yeah, it's just easier in life. 0:22:47.119 --> 0:22:49.600 That's a life note. Go with the grain, go with 0:22:49.640 --> 0:22:56.639 the flow. Actually I don't necessarily I don't necessarily espouse that, agreed. Okay. So, um, 0:22:56.800 --> 0:22:59.640 one of the other things you're gonna learn is um focus. 0:23:00.160 --> 0:23:02.280 And you kind of touched on this earlier, but you 0:23:02.320 --> 0:23:05.800 were kind of talking about how you you want to 0:23:06.000 --> 0:23:08.720 stop You like, if you if you go to hit 0:23:08.760 --> 0:23:11.160 a board or a piece of wood or a piece 0:23:11.160 --> 0:23:14.720 of concrete or something like that, your brain's gonna scream 0:23:14.840 --> 0:23:17.880 stop dummy. Yeah, So how do you get over that 0:23:17.920 --> 0:23:22.240 when you go into training where you're trained to break boards? Well, 0:23:22.280 --> 0:23:25.880 I mean you you focus. You try to focus as 0:23:25.920 --> 0:23:28.800 if the the board that you were breaking as several 0:23:28.840 --> 0:23:34.359 inches behind the actual board. To participitate or encourage that 0:23:34.440 --> 0:23:37.120 follow through. But they also make a very good point 0:23:37.200 --> 0:23:41.159 about breathing. And if you saw Karate Kid, what does 0:23:41.200 --> 0:23:44.240 he say with all everything, remember, breathe then breathe out. Well, 0:23:44.280 --> 0:23:47.879 they actually do that to prepare for the ice breaking. Yeah, 0:23:47.920 --> 0:23:50.239 so it's breathing is very important and then you know 0:23:50.359 --> 0:23:52.800
