Just Think

Totally self working! Any card, any pen, any deck, any paper! No questions, no switching, no forcing! A spectator is asked to write the name and suit of any playing card on any piece of paper. The paper is crumbled up and hidden. The magician removes one playing card from a regular deck. This card is placed face down onto the spectator's hand. For the first time, the paper is unfolded, the card turned over, they're identical! The card on their hand is exactly what was written down!
