MAGIC STONE EGG Egg McChameleon Another gem plucked from the A.S. & S. mirabilia. The shape and size of a hen egg, this opaque stone (or matte-finished glass - we're not sure which) is interesting in itself. Touched with a red penlight in a dark room, the entire egg becomes a brilliant ruby color. Blue light/blue egg, etc. Fun and fascinating, and with a little sleight of hand, a sure way to convince the plebeians that you have some mysterious metaphysical power.
