An astonishing double-punch prediction!
The performer explains that he has two prediction cards. One is placed in full view. A spectator mixes a packet of cards, which consists of several jumbo cards cut into quarters. The quarter-pieces are placed face up on the table and some are turned face down. Now, any outside row (or column) a spectator selects is folded inward onto the next row (or column). The folding over of rows is repeated until all the cards have been assembled into one pile. The performer spreads the cards and shows four face-down cards, the exact number he predicted. The four face-down cards are turned face up to show they form a single card, but one of the jumbo quarters does not fit. When the performer shows his second prediction, it is indeed correct: It also has a mismatched corner!
Easy to do! No set-up required, always ready! Comes complete with all the cards.
