the spectator thinks of any card in the deck and the magician lays 3 groups of cards until the deck has run out then you ask if there card is in the first group if not then ask if its in the second etc whatever group they say "yes my card is in here" you put that group of cards inbetween the other two stacks of cards do this 3 times on the last time put the stack of cards on top of the other's then lays down 9 cards and ask's if they can see there card if they say yes its the last card (9th) if they say no lay another 9 cards underneath now they SHOULD say yes and its the 10th card.......this is a self working card trick...
