A few weeks back, I got the chance to spend a whole weekend with one of my nephews. His mommy and daddy dropped him off for a weekend with Auntie M and Uncle B – it was a blast. To make simple bathtub paint, I took a muffin tin and filled each cup with a little bit of foaming shaving cream. I added a couple of drops of food coloring into each cup and mixed with my fingers until the color was fairly even.
I think Mr. R had a blast. At first the texture kinda threw him off, but eventually both hands were smearing the colors all over the bath walls. I was cracking-up the whole time watching him discover how the shaving cream felt and worked as paint. Eventually, all fingers and toes were pruney, the water was a rainbow of different colors, and it was story time. This was such a simple and fun activity. The shaving cream didn’t leave any dye behind on my tile or grout, but I would suggest you test it before letting your kids go wild.
