Two paintbrushes
Small saucepan (if using a microwave, you will need a glass 1-cup measuring cup)
Corn syrup
Red or brown water colors or makeup blush or rouge
One envelope
unflavored gelatin, like Knox brand.
In a small saucepan, sprinkle gelatin over ¼ cup of cold water. Let stand one minute. Then stir over low heat until all of the gelatin is completely dissolved. (Microwave Directions: In a 1-cup glass measuring cup, sprinkle one envelope gelatin over ¼ cup of cold water, let stand 2 minutes. Microwave on HIGH {Full power} for 40 seconds, stir well, then let stand 2 more minutes until gelatin is completely dissolved. Let it cool completely before using!)
Paint or smear a thin coat of corn syrup on your skin the shape you want your scabs to be.

Cover the syrup with a thick layer of cornmeal. Let it sit for 2 minutes, then carefully tap off the excess.
Use the paints or makeup to color the cornmeal patches.
With a paintbrush, paint the COOLED gelatin mixture over and around the scab. Do this VERY GENTLY so you don't brush off the cornmeal. (The gelatin "seals" it in place).
