When I first started off this blog, my younger sister told me I should do this activity. I finally got around to it. It fits perfect in our St. Patrick’s week. My husband started the bath while I mixed up the colors. This is just shaving cream mixed with food coloring. I then poked my head in the bathroom and said, “I forgot. Where did the leprechauns hide all their gold?” After they said at the end of the rainbow, I came in with this foamy bath paint. The kids had a blast decorating the walls and then had even more fun when they realized they could decorate themselves.
