Mix shaving cream and a tablespoon or so of Kool-Aid to make a tinted, scented finger paint material for small children. A cookie sheet makes a good table on which to mix paint colors and serves as a play surface for the kids to swirl the shaving cream. Use different flavors of Kool-aid to achieve different colors. This finger paint washes off very easily. Kids like to squish the cream through their fingers and move it around on their work surface.
