To prevent gelatin from drying out, (no colors or other colors may be used) mix five drops of red food coloring with 1/4 teaspoon of water, and add in one drop of yellow and blue food coloring. Now add 1 teaspoon of very hot water and then add 1 teaspoon of gelatin. Modify it by adding 6 drops of the color mixture (red, blue, and yellow) that I previously mentioned, with 1 teaspoon of very hot water and 1/4 teaspoon of glycerin. Add this mixture to 1 tablespoon of gelatin and stir quickly. Other colors may be used according to portion. You will learn how to use it later, and note that it can be used as fake skin - cuts, etc. -.
