Two spectators each remove 8 cards. One removes only Red's whilst the other, only Black's. They are then riffle shuffled into each other, one face up and one face down. Now through a series of spectator controlled cuts and shuffles, the packet is left in disarray. Then the performer snaps his fingers and showhow the black's are all facing one way and the red's the other. But it appears like the performer has made a mistake and one black card is mixed in with the red's. But, he had a little prediction on the table from the beginning which somehow predicted it all!
