Let a spectator choose absolutely free a card (no force) and let him sign the card. Now you rip off a corner of the signed card. You remove your watch and give it to the spectator to examine. Take the watch back and lay the rip off corner on the glass of the watch. Wave your hand over the glass of the watch and let the magic happen. The rip off corner is now inside the watch! It has melted right through the glass! And it is exactly the tear off corner which can be examined. Everything can be examined clearly now. And the watch can be given as a most impressive "timeless" souvenir.
The DVD will teach you how you can create this fantastic effect.
