i like these 2 recipes-
Sun Clay
Ingredients: 2 cups salt, 1 cup cornstarch, and water.
Mix the salt and 2/3 cup water in a saucepan. Cook over medium heat for 4 to 5 minutes, stirring until the salt is dissolved. Remove from heat. In a separate bowl, slowly add 1/2 cup water to the cornstarch. Stir until smooth, then add to the salt mixture. Return to low heat and cook until smooth, stirring frequently. Store in a sealed plastic bag.
Place the clay on a tray or paper plate and have children work outdoors or in a sunny area indoors. Give children a lump of clay to model. Children may decorate their sun sculptures with small stones, leaves etc..
Place the finished items in the sun to dry. Challenge children o predict how long it will take for the sculptures to dry. When this clay hardens in the sun, it won't crumble.
The Best Cooked Play Dough
Ingredients: 1 cup flour, 1/2 cup salt, 2 teaspoons cream of tartar, 1 cup water, 1 tablespoon oil, food coloring.
For group settings double the recipe.
Combine flour, salt, and cream of tartar in a saucepan. Mix liquids and gradually stir them into dry ingredients. When mixture is smooth, cook over medium heat, stirring constantly until a ball forms. Remove from heat and knead until smooth. Can use unsweetened Kool-Aid instead of food coloring. The Kool-Aid will color it and make it small great.
