1/2 cup cornstarch
3 Tbsp. sugar
1/2 tsp. salt
2 cups cold water
In a medium pan, mix all the ingredients together to make the finger paint. Cook over low heat 10 to 15 minutes. Keep stirring the finger paint mixture until it is smooth and thick. After the finger paint has thickened take the pan off the stove and let the mixture cool.
After cooling, divide the finger paint into storage containers depending on how many colors you would like. Add a few drops of food coloring to each container. Stir the coloring in to the paint to determine the shade of color. You're ready to finger paint! Cover tightly when storing.
3 cups water
1 cup cornstarch
In a medium saucepan, bring water to a boil. Dissolve cornstarch in a separate bowl with water. Remove boiling water from heat and add cornstarch mixture. Return to heat, stirring constantly. Boil until the mixture is clear and thick (about 1 minute). Remove from heat.
As the mixture is cooling, divide into separate bowls and add food coloring. Let the children carefully mix in the coloring.
Add 1 tbsp of glycerin to make the mixture shiny. You can find glycerin in most drugstores or pharmacies.
