Ice-cube Finger Paints
Now, we're not saying this twist on finger-painting is necessarily cleaner than the regular version, but it is a fun break from the norm. Drop some food coloring into ice-cube trays and fill them carefully with water. When they're frozen, let your kids paint with the colorful cubes. The cleanup crew will probably go through an entire roll of paper towels, but your kids will be begging for more painting time.
