F.C.O.C. by Fairmagic- A new twist for the card on ceiling
Two cards are chosen by the audience. The first card appears by throwing the deck on the ceiling (or wall). A corner from the second card is torn off and the card vanish. When they look up to the ceiling again, the first card had changed into the second card with the missing corner!
