Making water color paint:
1 tablespoon white vinegar
2 tablespoons baking soda
1 tablespoon cornstarch
1/4 tablespoon glycerin
plastic bottle caps or paint pans, or styrofoam egg carton
red, yellow and blue food coloring
1.Mix vinegar and baking soda together in a small bowl.
2.When mixture stops foaming, add cornstarch and glycerin, mixing well.
3.Pour mixture into bottle caps or paint pans
4.Add several drops of a different food coloring to each pan or cap or carton cup. Stir until the color is well-mixed. Be sure to add plenty of coloring, since the tint will lighten upon drying. Mix primary colors to make secondary colors. For intense colors, try kool-aid or food coloring paste (Wilton makes great food coloring pastes).
5.Let set overnight to harden.
This makes a good substitute for purchased watercolor sets, but tends to be more powdery.
