My kids love to play with the hair dryer. So, I thought why not let them paint with it too. We took out a big box and taped our paper to the bottom (so it didn't blow away). Then I let the kids put in what color paint they wanted an we tossed in the balls. We the plastic, golf balls but I'm sure any light weight ball would work. We turned the dryer on the coolest setting and began blowing the balls around. We discovered the balls with the holes in them worked the best. Next time we do this I will get out the smaller travel dryer, the big one was a little heavy for little hands.
