Effect: Begin the trick by what I call riffling the deck. (If you don't know what I'm talking about, see below.) Tell the spectator to say stop. Where you stop you cut the deck. The card on top of the bottom pile is the spectator's card. Tell the spectator to look at the card and put it back where it was. You put the top half of the deck back on top of their card. Now you lay the cards face up so you can see them all. You pick a card and that is the spectator's.
Card Trick: The trick is really simple. It makes some people laugh at how simple it is. (Editor's note: but DON'T tell them!). All you do is this: while they look at their card, turn the top pile you cut over so that you can see the face of that card. Then you'll know that the card you're looking for is right next to it. It is always best to do this innocently so the spectator doesn't suspect anything. You don't have to lay the cards face up - it is good to customize this effect for yourself. I recommend you pretend to get it wrong the first time, to fool the spectator.
Riffling the deck: Hold the deck in your left hand, in the normal position for dealing. Place your right ring, middle, and index finger on the edge of the cards that is facing outward. Place your right thumb on the middle of the top card. With your right fingers, starting at the bottom of the deck quickly brush your fingers up.
