Blowing bubbles never seems to lose its charm for little kids, but here's a colorful way to make a good thing even better.

To start, stir 2 tablespoons of tempera paint or 15 drops of food coloring into a 1/2-cup of bubble solution. Then tape a large piece of paper to a fence or between two trees and have your child blow the bubbles against it. The end result will likely be more about the process than the final product, but he'll love watching the bubbles hit the paper and burst into vibrant circles and splatters.
