1 cup sand 1/2 cup cornstarch 1 tsp. cream of tartar 3/4 cup hot water
Mix sand, cornstarch and cream of tartar in an old saucepan. Add hot water. Cook over medium heat, stirring constantly until the mixture is very thick. This will only take a few minutes. When slightly cooled, form clay into castles or structures. Allow several days to dry. We used this clay during Beach Week to make permanent sand castles. The children shaped their castles and then inserted toothpicks for flagpoles where they wanted flags to go. Once dry, we glued felt flags to the end of the toothpicks.
