Another trick involving a forced card, the Envelope Predictor is basically a self-working trick. The magician removes an envelope, sealed, and places it aside. He then shuffles and has the spectator cut the deck. The spectator removes a card that just so happens to match the card in the envelope! Follow these steps.
Instructions
1. Begin by setting everything up. First, choose the card to eventually be forced on the spectator. We will use the 8 of Spades.
2. Place the 8 of Spades from Deck #2 in an envelope and seal it shut.
3. Prearrange Deck #1 so that the 8 of Spades is on top of the face-down pile.
4. Using either the cut deeper force or the cross cut force, both of which have their own eHow tutorials (see Resources below), make sure that his chosen card is the 8 of Spades.
5. Both of these forces seemingly reverse the order of the deck, making it seem like the spectator has a free choice. In reality, he is choosing the top card, the 8 of Spades.
6. Have him reveal the chosen card. Now bring back the envelope.
7. Open the envelope and remove the card, face down, to add suspense. Eventually, turn it over to reveal it is the same card.
