Looking for new ideas to fill your summer days? Try this easy, hands-on science experiment using just four common items you probably have at home. Our Traveling Rainbow is simple and visual for children of all ages—and it shouldn’t make too much of a mess either. (We know exploding baking soda volcanos aren’t for everyone!)
For this water-based activity, you’ll also need cups (or jars), food coloring, and paper towel.
Once set up, they all work in harmony to create a blended array of colors that are sure to wow your little one. The colors will travel right before their eyes! To show you how it’s done, LCG’s Charlotte Armitage and her son, Ethan (9), created their own Traveling Rainbow at home.
Watch their experiment in action and then give it a try yourself!
Have your child describe what they see. Are the colors blending in the middle to form new colors? What would happen if you linked two different colors? Which one is their favorite? Tell us!
Snap a picture, share it on social, and tag your school. We’d love to see your rainbow!
