Best Card Tricks Revealed - THE SURPRISE

When you have discovered a card, the following plan will make a striking termination to the trick. Get the card to the bottom of the pack, and tell one of the spectators to hold the cards by one corner as tightly as he can.
Give them a sharp rap with your finger,—not with your hand,—and all the cards will be struck out of his hold, and fall on the floor, except the bottom card, which will remain between his finger and thumb. It has a rather more dashing effect, if you put the chosen card at the top, and strike them upwards, when the whole pack will fly about the room, like a flock of butterflies, only leaving the top card in the person’s grasp.
