1 cup Cornstarch
1 1/2 cup Water
16 oz Baking Soda

Directions:

Combine cornstarch and baking soda in a large saucepan. Stir in water and cook over low heat until the mixture begins to thicken and form a ball. Remove from heat.  Dust the countertop lightly with cornstarch and turn the clay out of the saucepan. When cool enough to handle knead the clay until smooth. Store the clay in a air-tight plastic bowl or large baggie. Clay is ready for use when completely cool. Can be stored refrigerated for up to 2 weeks. Make figures by modeling to shapes or rolling about 1/4 to 1/2 inch thick and use cookie cutters. Allow to air dry over several days or bake at 300°F for 25-35 minutes. Decorate the dried figures with paints and markers.
