Blow Up trick El Duco
Great for Bar & Restaurant Performances The magician displays a deck of cards. He spreads the cards and hows them on both sides. A spectator selects any card (no force) and may even sign it if they like. The selection is replaced in the pack and the entire deck is put back into the case. The magician now points out a small hole in the bottom of the case. He then places one end of a drinking straw into the hole and asks the spectator to blow in the other end. The spectator's card pops up out of the deck!
