Fun Finger Paints 1 envelope unflavored gelatine 1/2 cup cornstarch 3 tablespoons sugar 2 cups cold water Food color, Wonder Colors, or Tempera (powdered or liquid) Liquid dishwashing detergent White shelf paper Soak gelatine in 1/4 cup warm water and set aside. In a medium-size saucepan, combine cornstarch and sugar. Gradually add water, and cook slowly over low heat, stirring constantly, for 5 minutes or until well blended. Remove from heat and add the softened gelatin. Divide mixture into separate containers for each color. For each color, add a drop or two of liquid detergent and then the coloring, drop by drop, until you obtain a shade you like. Food coloring is best for this. Store paint in the refrigerator for up to 6 weeks. If you would like to make sure the paints remain usable for a long time in storage, add a few drops of glycerin to the mixture when you add the liquid detergent.
