• 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

Directions:

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.

These paints tend to be more powdery than the store sets
