I saw this idea in the February 2008 issue of Family Fun magazine, on page 89. It’s from an article on The Kids Concoctions Couple, John & Danita Thomas. We just got our first chance to try it last summer. A big hit, but messy!
Mix equal parts cornstarch and water, and color with food coloring. Paint on driveway or sidewalk with brushes, or spray onto sand or snow sculptures.
