Next, I added a child to a bath tub and let him go wild.
I washed the paint off right after bath time and it did not stain my tub at all. I can not vouch for white tubs, as I have a yellow tub that only a true 1980's house would possess. My little guy was in love with this activity. He has asked for a repeat of it again tonight. This time we added even more colors. Plus, he got bold and decided to abandon the brush in favor of his hands. It sort of defeated the purpose of bath time, since now his hands look faintly rainbow colored, but it was so worth it.
