WEBVTT - How do they create patterns in a baseball field?

0:00:00.520 --> 0:00:03.840
<v Speaker 1>Welcome to Brainstuff from house stuff works dot com where

0:00:03.840 --> 0:00:15.160
<v Speaker 1>smart happens. Hi, I'm Marshall Brain with today's question, how

0:00:15.160 --> 0:00:19.520
<v Speaker 1>do they create patterns in a baseball field? Groundskeepers at

0:00:19.520 --> 0:00:24.680
<v Speaker 1>baseball parks have traditionally created checkerboard, diamond, and angle patterns

0:00:24.720 --> 0:00:28.040
<v Speaker 1>in the field. These patterns have become more elaborate in

0:00:28.080 --> 0:00:32.280
<v Speaker 1>recent years. Baseball fans might remember the star patterns created

0:00:32.280 --> 0:00:36.960
<v Speaker 1>at Coors Field in Denver to commemorate the All Star Game.

0:00:37.400 --> 0:00:40.479
<v Speaker 1>These designs are not all that complicated and could be

0:00:40.520 --> 0:00:44.479
<v Speaker 1>easily duplicated in your own lawn. The designs are created

0:00:44.560 --> 0:00:48.839
<v Speaker 1>through a process called lawn striping. To create lawn striping

0:00:48.880 --> 0:00:52.840
<v Speaker 1>designs of your own, you only need two pieces of equipment,

0:00:52.920 --> 0:00:57.080
<v Speaker 1>a lawn mower and a roller. Many professional groundskeepers use

0:00:57.160 --> 0:01:01.360
<v Speaker 1>old fashioned real mowers to cut a stadium's grass. Attached

0:01:01.480 --> 0:01:03.840
<v Speaker 1>just behind the blades of the mower is a lawn

0:01:04.000 --> 0:01:08.319
<v Speaker 1>roller that bends the grass down. Some lawnmower manufacturers are

0:01:08.319 --> 0:01:12.280
<v Speaker 1>beginning to make riding mowers with full with rollers mounted

0:01:12.560 --> 0:01:15.160
<v Speaker 1>to the rear of the mower to make this task easier.

0:01:16.680 --> 0:01:20.200
<v Speaker 1>Whatever pattern you make is revealed by the light shining

0:01:20.200 --> 0:01:23.360
<v Speaker 1>off the bent grass. A checkerboard design is created by

0:01:23.400 --> 0:01:26.959
<v Speaker 1>passing over the grass in side by side rows, first

0:01:27.040 --> 0:01:30.520
<v Speaker 1>going north to south, then making east to west stripes

0:01:30.560 --> 0:01:33.920
<v Speaker 1>in the grass that intersect the north to south stripes.

0:01:34.400 --> 0:01:37.759
<v Speaker 1>In this way, you alternate the way the grass bends.

0:01:38.160 --> 0:01:41.000
<v Speaker 1>When you look at your lawn, the stripes of grass

0:01:41.120 --> 0:01:44.720
<v Speaker 1>leaning away from you look lighter. This lighter green is

0:01:44.760 --> 0:01:48.480
<v Speaker 1>caused by the sunlight reflecting off the entire blade of grass.

0:01:48.520 --> 0:01:51.880
<v Speaker 1>In the darker green stripes formed by the blades of

0:01:51.880 --> 0:01:55.680
<v Speaker 1>grass leaning towards you, the sunlight is reflecting only off

0:01:55.680 --> 0:01:59.120
<v Speaker 1>the tips of the blades. Different grasses can be used

0:01:59.160 --> 0:02:03.480
<v Speaker 1>to accentually the striping effect, including rye grass, fescue, and

0:02:03.560 --> 0:02:06.960
<v Speaker 1>blue grass. You won't see such a big contrast between

0:02:07.000 --> 0:02:10.240
<v Speaker 1>the stripes colors if you have a warm season grass

0:02:10.240 --> 0:02:13.960
<v Speaker 1>such as bermuda or zeisa. Watering the grass after mowing

0:02:14.040 --> 0:02:19.359
<v Speaker 1>can make your patterns stand out even more. For more
