Gemini Twins Effect: A magician removes two cards from a deck and place...
Effect: Spectator chooses a card. The card is placed randomly back in the deck. The magician explains about magic breath, that it will magically make a card appear where a person wants it to be. He hands the deck to the spectator, tells him to think of a number in his head, to breath on the deck, and to deal off that many cards. The spectator flips the last card and finds that its not his. The magician then deals off the exact same number and flips the last one, showing that it's his card.
This trick requires a person to be able to pass a card to the top of the deck. Use whatever method you're comfortable with. After shuffling the deck, let the spectator choose a card, then place it back in the deck. Pass the card to the top and hand the deck to the spectator, explaining about magic breath. Tell him to breath on the deck and to count off the cards according to a number he chooses into a neat pile on the table. Flip the last card counted to show that it's not his. Take the deck back from the spectator, pick up the pile on the table and place it back on top of the deck while telling the spectator that he doesn't have magic breath, only bad breath. The selected card will now be at the exact number into the deck that the spectator counted. Ask the spectator what his number was, breath on the deck, and count off that many cards. Flip the last one to reveal his card.
