The Glide Force
The magician asks the spectator for a number 1-52, the magician then pulls cards from the bottom of the deck until the spectator's number has been reached and shows the spectator the card selected. However, the card selected is actually the original bottom card of the deck.
How It's Done
First peek the bottom card of the deck, then perform the Glide. Pull out cards from the bottom of the deck (here you continuously take the second to bottom card, leaving the real bottom card in place) until you reach the spectators number, except before reaching the number close the glide with your pinky and grab the actual bottom card and show it to the spectator.
