Messy but fun and always unique!
We had a old box from moving and some washable paint. We used old shoes and made swinging art. First I let them use the paint bottles and swing, squirting the paint onto the box. When they had a good amount of paint on the box they laid on theirs bellies and swung rubbing the paint around with their shoes as they went. I thought this would be even funner to do bare foot but decided not too with the wood chips everywhere. Next time I would try to find a swing with grass under and maybe use a white box cause the brown made it look dirty. Either way the kids didn't mind and love trying this activity out.
