931 - What is a rainbow, and how does it form after rain?

A rainbow is a colorful, curvy shape that appears in the sky after it rains. It forms when the sun shines through tiny drops of water in the air.

Here's how it happens:

1. When it rains, the rain makes lots of tiny drops of water in the air.
2. The sun shines through these drops of water.
3. The light gets bent, or "reflected," when it passes through the water drops.
4. The light is split into different colors, like a big colorful puzzle.
5. We see the colors in the sky, and that's a rainbow!

So, the next time you see a rainbow, remember: it's like a big, beautiful painting in the sky, made by the sun, water, and light.
