A small coin (10p/US quarter) is tipped from a purse and marked with a sticker bearing a spectator's initials. It is then taken into the performer's closed fist, the other hand being shown otherwise empty.
The purse is then laid flat across the top of an examinable glass tumbler so that the top of the container is completely covered.
The hand is then brought down with a slap onto the top of the purse, opening as it does so and instantly a coin is seen and heard to penetrate the purse and fall into the tumbler.
With both hands clearly empty, the purse is lifted away to reveal that it is indeed the signed coin that has penetrated through and into the glass.
