Effect
The spectator selects a card.
You RIP out the center of the card. The spectator writes their initials on the center piece and keeps it.
Take any wine or champagne glass and slam the card at the glass. The card Links onto the stem! You can see it spinning round.
The spectator holds the top and bottom of the glass. You pull the card off the glass, the center fits and they keep the card!
