You borrow a coin and a pack of cigarettes from the audience. Ask a spectator to sign the coin. Then you slide the plastic wrapping partly off of the cigarette pack. With a quick gesture, the signed coin in your hand will penetrate the plastic wrapping of the cigarette pack! Purely technical and no gimmick used.
