I was skeptical of this, but decided to try it. Unfortunately, the ONLY way to use this is with your
stockinged-foot. You also need to either buy a magnetic quarter from Penguin, or construct one by
gluing a washer to the back of a real quarter. There is slight-of-hand necessary to this trick. It
cannot be done without removing your shoe, nor be done wearing (white, cotton) gloves. All this
makes it unusable for me, but your venue might be different.
