1 tbsp. White Vinegar
2 tbsp. Baking Soda
1 tbsp. Cornstarch
1/4 tsp. Glycerin
Plastic Bottle caps or
Red, Yellow, and Blue Food Coloring
Mix vinegar and
baking soda together in small bowl. When mixture stops foaming, add
cornstarch and glycerin. Mix well. Pour mixture into plastic bottle caps
or paint pans. Add several drops of different food coloring to each pan.
Stir until the color is well mixed. The tint may look lighter when dry, so
be sure to add plenty of coloring. To make green, add equal amounts of
blue and yellow; for purple, equal amounts of red and blue; for brown 1
drop blue, 1 drop red, and 2 drops yellow. Paint will be liquid at this
stage. Let sit overnight to harden.
