The Split Deck Effect: Performer asks for the deck to be "cut". The cards are removed from the deck to find they have really been cut down the middle! Performer determined to finish has the spectator pick any card from one half of the deck. Another spectator selects a piece of card from the other half. The cards are then placed together to show a match! Have a couple try it out and show how great a match they are!
The cards can be spread face up to show all the cards are different.
