1/2 c. salt
1 c. flour
1 c. water
1 tbsp. vegetable oil
2 tsp. cream of tartar
Food coloring - add drop by drop until you like the color, approx. 10 drops = light; 20 drops = strong color

Mix all ingredients in a saucepan and cook over medium heat, stirring constantly, until a ball forms. Voila! You have play dough.

Since this recipe makes about 2 cups, before cooking and adding color, you can divide into 4 parts and color each part differently. Each color must be cooked separately.
