CRUMMY COOKIE TRICK
A penny is placed on the back of a spectator's hand. The magician waves a cookie over the coin and it magically becomes a dime. This is repeated with a second penny, only this time the penny shrinks down to a tiny penny! Now the cookie is tossed into the air where it magically vanishes in mid-air! If that's not enough, the cookie reappears in the magician's pocket. Finally, the magician takes a bite out of the cookie, then magically restores it to a solid cookie once again!
