Bottoms Up Card Trick
Effect: A pack of cards is fanned out in front of a spectator. The magician runs his fingers around the card fan and the spectator is asked to tell him when to stop his fingers on a card. This card is shown to the audience, replaced in the pack and the pack handed back to the spectator to shuffle. The magician then reveals the card which was chosen
Method: Ask a spectator to shuffle the card. When he/she hands them back to you note the bottom card. That is going to be their card.
Start by fanning the cards out . Run your finger across them and ask the spectator when to stop. When he/she says to sto , put your thumb on that point.
While your thumb is on that point, use your other fingers to slowly work the bottom card under your thumb. As you pull the cards off the top of the deck with your thumb, slide the bottom card under the other cards and pull them off the deck and show the spectator his/ her card . This is where you take over. Since you already know the card you can have the spectator cut, shuffle, e.t.c .
Good routine to try out
Start flipping the cards from the top of the deck over onto the table . When you flip their card over, continue flipping for another few cards , then say, "I'll bet you that the next card I flip over will be yours!" They'll think you messed up because their card is already flipped over on the table. When they say, "you're on!, reach over and flip their card, which is already on the table, face down. They'll be amazed.
