Shaving cream art - Spread out some foamy shaving cream on a flat surface or in a tray pan. Smooth it out a bit. Then use either food colors or liquid watercolors and put blobs of color with a paint brush or eye dropper. Liquid Watercolors give the most vibrant color! Next swirl the colors with a stick. We used a kebab stick. You could use a toothpick, popsicle stick, or even a stick from outdoors. If you had a fancy comb you could use that too.
