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
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 stop, put your thumb on that point in the deck.
While your thumb is on that point, use your other fingers to
slowly work the bottom card under your thumb.
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.
