Snake Skin

Remember those days in elementary school when you put glue all over your hand, let it dry, and then pretended your skin was peeling off? This is based on the same idea.
I mixed some clear glue with a couple drops of green food coloring, then had him paint it on a bumpy plastic cookie tray. Much later I peeled it of for him and he had green snake skin (well we decided to make it green gecko skin).
