Directions On a dry, warm day give your child a plastic bucket of water, one or two paintbrushes, and an old sponge. Find a safe driveway, wooden deck, cement wall, or stretch of pavement, and let her paint large pictures or patterns with the water onto the cement or wood surface. Pictures will dry and disappear, exciting your child with endless possibilities. Step into the bucket to make footprints, splash or drip water off fingertips. Use the sponges to press onto the hard surface or squeeze water into patterns.
