I was flipping through the book this afternoon, and came across this experiment. We've done it before and it's SO easy...I mean little kid easy, but it's fun and makes something beautiful. I asked Cody if he'd like to try it out and he was game.
Take a paper towel and draw a dot of color with a marker.
Cody tried all the markers we could find and really liked watching the colors spread across the paper towels. He said his favorite is the rainbow one - Top center in the picture above :) My favorite is the orange explosion! So pretty!
