Fake Flesh Ingredients 2 tablespoons corn starch4 teaspoons water2-5 drops red food coloring1/2 teaspoon cocoa mix (with marshmallows or without) How to Make Mix together the cornstarch, food coloring, and water in a bowl.After you have a smooth consistency, mix in the cocoa powder. It's okay if the cocoa forms little clumps (they'll look like blood clots).Use your fingers to press the mixture against the side of the bowl to form shapes. If you use your hands, you'll get crumbly edges, so a mold (the bowl) is best for a smooth effect. You may wish to mix in a little more cornstarch or cocoa mix to firm up or darken your organs.

If you want a more flavorful flesh, use unsweetened cherry or berry drink mix instead of food coloring and cocoa. You could use the sweetened version, too, but the resulting flesh might be sticky.
