**Why does a rainbow form after it rains?** After it rains, there are alot of water drops in the air. The sun comes out and white light strikes the water drops. They all act like prisms and seperate the light into colors: a spectrum. Rainbows appear when the water drops reflect the light. Rainbows have no end; they are circles. To see a rainbow the water drops have to fall in front of you and the sun has to be behind you. **

Interesting Facts:**
 * Sometimes the light bounces off the water drops more than once. This makes a weaker second rainbow: a double rainbow. The colors of the second rainbow are reversed because there is said to be additional rainbows that are to dull to see.
 * Bright rainbows are from larger water drops and dull ones are from small drops.
