This growing rainbow experiment is perfect for some colorful fun!

How to do this activity

A. Materials you need
paper towel

markers
art tray
cups
water
scissors

B. Set-up

Rip off one sheet of a paper towel and fold it in half. We used the Bounty brand since it soaks up better than other brands. 

Cut the paper towel just a little bit! 

Use Crayola brand markers to color bands of the rainbow on either side of the paper towel. Do this on both sides of the paper towel.


C. Activity


Grab two small cups of water. Dip either side of the paper towel into the water. Make sure that only a little bit of the paper towel is in the water on both sides. 


Watch to see the rainbow grow to the center! 


This is such a cool experiment and is perfect for St. Patrick's Day!
