David Stone performed this in our shop and it floored everyone in the room.
Mickael spent almost an entire year working on REWIND. The result is unbelievable, yet easily doable by anyone.
A spectator selects a card from your deck; you fold the card in quarters and have the spectator sign its face. Once the card is signed, you tear it into two, then four pieces. The pieces are clearly separate from each other. You place two of the pieces between your lips and hold the other two at your fingertips. With no possible funny business, you restore the two pieces you were holding in your hands, leaving nothing to hide or add! Take the third piece at your fingertips, and as impossible as it seems, it becomes fused with the rest of the card as you simply hold it in place -- an impossible and very visual restoration. Now bring the card with the missing corner to your lips and the spectators will see the last piece melt into place in full view! Show your hands empty, which they really are, and don't forget to return the card to the spectator, who will confirm that the card is indeed the one he signed.
