Mind reading with cards
In the next clip, David Blaine riffles through a deck of cards and wants you to remember one. He then tells you exactly what card you are thinking of.
Explanation: This one is really simple. The reason everyone remembers the queen of spades is that it is the only card clearly visible as he riffles through the deck. He only waits a little longer when he gets to the card he wants you to remember. That's why this trick works on almost everybody.
