Use a small copper coin -a penny will do- and rub your sub's skin with ith using long strokes. You do not even have to press very hard, but make sure you run the same place at least a dozen times. What looks like a ferocious welt will appear on the skin. It will disappear quite fast, but if you only want it to take a very impressive picture, this will do.
