St. Patrick's Day is just around the corner, and with all of the rainy weather we've been seeing, we've also been keeping an eye out for rainbows. Who else do we know spends a lot of time looking for rainbows? Leprechauns! While we love seeing rainbows outside, we also thought it'd be fun to make some of our own. All you need is a CD, a flashlight, and a dark room to create colorful rainbows in your home.This is a great project for kids explore different colors of light. When the colors are all mixed together, like with the beam of light from the flashlight, we see white light. But when the light hits the tiny grooves on the surface of the CD, that splits the light into its different colors, creating the rainbow you see on the wall! Ask your kids to compare the rainbows they see on the wall with rainbows they see in the sky. What colors can you see? Where are some other places you can find rainbows? Have fun exploring light and rainbows!
