Sky's Blue Bounce
Why is the sky blue during the day?
Look up on a clear afternoon, and the whole sky is painted one impossible color: blue. Not the trees, not the dirt, not the ocean down the road — the air itself, glowing like someone spilled a bottle of paint across the ceiling of the world. So where does all that blue come from? Plot twist: it was hiding inside the sunlight the whole time.
Sunlight looks plain and white, but that white is a disguise. Tucked inside every sunbeam is every color at once — red, orange, yellow, green, blue, violet — all stacked together. Split them apart, the way a raindrop does, and you get a rainbow. The sky's blue is really just one of those colors, caught and set loose.
