Need a fun idea for a backyard party? Dip rubber spike balls in tempera paint, then toss them at a paper-covered wall to create monster-shaped splats. When the paint dries, draw on zany faces to make your mural come alive.
To avoid wayward splatters, paper a larger area than you plan to paint.
Use pushpins or tape to cover the side of your garage or fence with several lengths of paper. Spread a drop cloth on the ground below to keep the paint-covered balls grit-free.
Squeeze each paint color into its own container. Roll a rubber spike ball in the paint to cover it, then stand about 5 feet from the wall and toss the ball at the paper. Repeat using other colors, if you like. Let the paint dry, about 15 minutes.
Use markers to draw on faces, features, and speech or thought bubbles. If you like, press on googly eyes. Use a hose to wash away any misses.
