messy

This one's messy but SOOOO much fun... have them make Oobleck (wear smocks and use cafeteria trays on desks) Oobleck is the only? or of the only materials that is both a liquid and a solid. It's cornstarch and water and it behaves in crazy ways. My kids love to do this activity one day and then debate if it is a liquid or a solid and why. Before the activity, they have to have the background knowledge of the qualitiies of liquids and solids.
