Speaker 1: Welcome to Brainstuff from house stuff works dot com where

2
00:00:03,840 --> 00:00:15,160
Speaker 1: smart happens. Hi, I'm Marshall Brain with today's question, how

3
00:00:15,160 --> 00:00:19,520
Speaker 1: do they create patterns in a baseball field? Groundskeepers at

4
00:00:19,520 --> 00:00:24,680
Speaker 1: baseball parks have traditionally created checkerboard, diamond, and angle patterns

5
00:00:24,720 --> 00:00:28,040
Speaker 1: in the field. These patterns have become more elaborate in

6
00:00:28,080 --> 00:00:32,280
Speaker 1: recent years. Baseball fans might remember the star patterns created

7
00:00:32,280 --> 00:00:36,960
Speaker 1: at Coors Field in Denver to commemorate the All Star Game.

8
00:00:37,400 --> 00:00:40,479
Speaker 1: These designs are not all that complicated and could be

9
00:00:40,520 --> 00:00:44,479
Speaker 1: easily duplicated in your own lawn. The designs are created

10
00:00:44,560 --> 00:00:48,839
Speaker 1: through a process called lawn striping. To create lawn striping

11
00:00:48,880 --> 00:00:52,840
Speaker 1: designs of your own, you only need two pieces of equipment,

12
00:00:52,920 --> 00:00:57,080
Speaker 1: a lawn mower and a roller. Many professional groundskeepers use

13
00:00:57,160 --> 00:01:01,360
Speaker 1: old fashioned real mowers to cut a stadium's grass. Attached

14
00:01:01,480 --> 00:01:03,840
Speaker 1: just behind the blades of the mower is a lawn

15
00:01:04,000 --> 00:01:08,319
Speaker 1: roller that bends the grass down. Some lawnmower manufacturers are

16
00:01:08,319 --> 00:01:12,280
Speaker 1: beginning to make riding mowers with full with rollers mounted

17
00:01:12,560 --> 00:01:15,160
Speaker 1: to the rear of the mower to make this task easier.

18
00:01:16,680 --> 00:01:20,200
Speaker 1: Whatever pattern you make is revealed by the light shining

19
00:01:20,200 --> 00:01:23,360
Speaker 1: off the bent grass. A checkerboard design is created by

20
00:01:23,400 --> 00:01:26,959
Speaker 1: passing over the grass in side by side rows, first

21
00:01:27,040 --> 00:01:30,520
Speaker 1: going north to south, then making east to west stripes

22
00:01:30,560 --> 00:01:33,920
Speaker 1: in the grass that intersect the north to south stripes.

23
00:01:34,400 --> 00:01:37,759
Speaker 1: In this way, you alternate the way the grass bends.

24
00:01:38,160 --> 00:01:41,000
Speaker 1: When you look at your lawn, the stripes of grass

25
00:01:41,120 --> 00:01:44,720
Speaker 1: leaning away from you look lighter. This lighter green is

26
00:01:44,760 --> 00:01:48,480
Speaker 1: caused by the sunlight reflecting off the entire blade of grass.

27
00:01:48,520 --> 00:01:51,880
Speaker 1: In the darker green stripes formed by the blades of

28
00:01:51,880 --> 00:01:55,680
Speaker 1: grass leaning towards you, the sunlight is reflecting only off

29
00:01:55,680 --> 00:01:59,120
Speaker 1: the tips of the blades. Different grasses can be used

30
00:01:59,160 --> 00:02:03,480
Speaker 1: to accentually the striping effect, including rye grass, fescue, and

31
00:02:03,560 --> 00:02:06,960
Speaker 1: blue grass. You won't see such a big contrast between

32
00:02:07,000 --> 00:02:10,240
Speaker 1: the stripes colors if you have a warm season grass

33
00:02:10,240 --> 00:02:13,960
Speaker 1: such as bermuda or zeisa. Watering the grass after mowing

34
00:02:14,040 --> 00:02:19,359
Speaker 1: can make your patterns stand out even more. For more
