This is a preschool classic and for good reason, it's always a hit! Fun, easy and surprisingly not very messy. 1. Gather your materials. You will need a box, a golf ball( or marbles for older kids), some paint and plain paper. 2. Cut your paper to fit inside your box. 3. Add a drop of paint. 4. Add the ball. 5. Rock the box back and forth and let the ball paint the paper. 6.Add another paint color if you want and keep rolling!
