00:06 Do you ever lie on your back outside on a sunny day?
00:09 There’s so much to see!
00:10 There are birds, and airplanes, and maybe even clouds, all way up in a pretty blue sky.
00:16 But why is the sky blue?
00:18 Why not green, or red, or any other color?
00:21 It all starts with light from our big, bright sun.
00:24 Now, it may not look like it, but the light from the sun is made of all of the colors
00:28 of the rainbow.
00:29 And you might already know that it takes many colors to make up a rainbow — red, orange,
00:34 yellow, green, blue, and violet!
00:37 All of the colors of the rainbow are in sunlight, all of the time.
00:40 It’s just that they’re all mixed together, so we don’t see them most of the time!
00:43 It’s kind of like when you’re painting and you mix together all the colors.
00:46 With paint, mixing all the colors makes brown, but when you mix together all the colors of
00:51 light, you get white light.
00:52 You can actually see the different colors in light sometimes!
00:55 One way to do it is by using a special tool called a prism, which is usually just a specially-shaped
01:00 piece of glass or plastic.
01:02 But you can even make a prism out of a glass of water!
01:05 Prisms bend light in a special way so that we can see all of the colors that make up light.
01:10 Say that I shine a bright flashlight into a prism.
01:13 The rays of light move in a straight line away from the flashlight.
01:16 When the light hits the prism, it separates into lots of different colors, and we have a rainbow.
01:22 So, the light is white when it moves in a straight line until it hits the prism.
01:26 Then, it bends, and we can see colors.
01:28 That’s a little like what happens to the light from the sun.
01:32 Rays of light leave the sun in a straight line, too, as they move through outer space.
01:36 They stay in a straight line until they reach the layer of air that surrounds the Earth.
01:40 Now, the air around the Earth is made of tiny little particles, or pieces, that we can’t see.
01:46 But they’re there!
01:47 If you try moving your hand back and forth really quickly through the air, you’ll feel
01:50 the air moving past your hand.
01:52 What you’re really feeling is all those little particles!
01:54 When the rays of light hit these tiny particles of air, they don’t just bend, like they
01:58 did when they hit the prism.
02:00 The light rays scatter, meaning that they go off in lots of directions, and bounce around.
02:04 And here’s the cool thing — some of the colors scatter more than others.
02:08 What color do you think scatters more?
02:10 [Squeaks guesses]
02:11 Right you are, Squeaks!
02:13 Blue is one of the colors of light that scatters the most!
02:16 So, as light from the sun moves into the air that’s way high up, the blue-colored light
02:21 bounces all over the place in the sky.
02:23 So when we look up, our eyes see a lovely blue sky.
02:26 But a lot has to happen to turn it blue!
02:29 So the next time you’re outside, don’t forget to look up.
02:32 You never know what you might see!
