Re-explain this explanation of rainbow formation so a 4th grader could understand it.

A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

Rainbows form sunlight passes through raindrops. Rain is thicker than air. Like how your hand has a harder time moving through water in the bathtub than through air, the sunlight slows down when it passes through the rain. The raindrops are so thick compared to the air that the sunlight also changes direction. It reflects off the rain droplets just like it would off a mirror but because it slowed down and changed direction, when it comes out of the rain droplet, it separates into the colors we see in a rainbow.
