I was very eager to try the marbling, but my son was eager to mix the lines of tempera paint into the shaving cream! We recently found this idea in a magazine or blog. In a tray, spread a layer of shaving cream. Drizzle with lines of tempera paint and use a toothpick, etc., to pull lines through the paint. Place a piece of paper on top and gently pat onto the surface. Remove and squeegee off the shaving cream, and you’ll have a lovely piece of marbling! If, that is, you can keep your children from using their hands to mix the paint and shaving cream together.
