Big Surprise !!!
Magician invites a spectator to select a card from a pack of few Jumbo cards. Spectator retains his selected card with him.
Then magician introduces a jumbo card fan containing seven cards . ( Note : the standard poker size Bicycle Card in picture of fan above is for size comparison only. It is not part of the prop) One of the cards is face down in the fan. He requests the spectator to spot his selected card in the fan. The spectator says it is not there.
Then magician says that the one face down card in the fan is the spectator's selected card. The audience think the magician is pulling their leg.
He asks the spectator to name the selected card. We assume the spectator says Queen of Hearts. When performer attempts to turn the fan around to show the opposite side, the entire fan of cards transforms into a giant size Queen of Hearts,( 8.5”x13.5”) which is the spectator's selected card.
We supply a specially constructed jumbo card fan, and the giant card , along with 20 jumbo cards including the queen of hearts .. for you to force the Queen of Hearts (use your own method of force) and instructions A "card trick" that packs flat, has a novel effect, and can be performed for a very large audience on stage.
