Scrub a dub dub, two artists in a tub

You will need: one muffin tin per child (unless they are willing to share nicely), food coloring (i promise it won't stain, unless you have tile with grout!), paintbrushes (you could just use your fingers), shave cream, squeegee (optional), children in need of a bath... What to do: Squirt shave cream into each muffin tin. Squirt a drop or two of food coloring into each blob of shave cream. Mix. Paint walls and body. (Easily wipe from walls with a squeegee!)
