Today we used marbles and a spinning top to paint! I watered down the tempura paint a little bit so the marbles could roll around a little easier. Annabel and I were both surprised to see the neat spray that the spinning top made on the paper. We placed a small sheet of white paper inside of a plastic lid (a pan with big walls would work too). Then Annabel used a spoon to drop paint onto the paper. Lastly we added the marbles and got rolling!
I really like this activity because it works so well with all ages. You can get complicated with colors or just let them mix freely.
