Walking Rainbow Science Experiment

Watch a rainbow come to life right before your eyes with this super simple but very colorful walking rainbow science experiment!

All you need are cups, water, food coloring, and paper towels.

“The empty cups fill up and mix colors to form all the colors of the rainbow. This happens because of Capillary Action! You should see results within a few minutes. If not, try a different type of paper towel.” – Science Kid
