Originally, I thought the kids would make rainbows or something.  I added some paint to shaving cream and loaded up a muffin tin.  They each received a baking sheet to use as their canvas.

Using cotton balls, toothpicks, spoons and their hands, they had a blast.

I think they were surprised that they could do whatever they wanted.

When they were done, I tossed the “brushes” and washed the dishes.  Clean up was a breeze.  I’m sure we’ll be doing this activity again.
