We decided to give bubble painting a try today. It was a little messy, but the kids thought it was really cool!
We mixed 1/4 cup water, 2 Tbsp paint, and 2 Tbsp dish soap in a little pie tin. A bowl would work fine too.
Blow in the tin with a straw and watch the bubbles expand. We pulled the bubbles over our paper and let it dry.
I did put some cardboard hearts on the paper to create more of a Valentine's Day image on it.
