Find the Lady Jumbo Cards

The magician shows three cards, two king of spades and a queen of hearts, and turn them face down. Then, while the magician shuffles the cards, he invites the spectators to follow the moves of the queen. One spectator selects a card, but it will choose the wrong one. The performer repeats it with another spectator, but even him won’t be able to find the lady. To end the magician asks to find one of the two king of spades. Strangely a third spectator will select the queen of hearts. Then, with a magic gesture, the performer changes all cards in queen of hearts… under the incredulous eyes of the spectators.
