David Blaine Card Jumps to Top Trick
The top card of the pack is turned face up to show it to the spectator and then turned face down, removed from the top and replaced in the centre of the pack. David then squares up the deck, clicks his fingers and the card is shown to have returned instantly to the top of the deck.
How David Blaine Achieves This Effect:
This trick uses mastery of a sleight of hand known as the double lift.
When the magician is apparently showing the top card, he is in reality performing a double lift to show the card that is really second from the top of the pack. The magician then simply removes the actual top card and places it in the centre of the deck thus leaving the card which he has already shown, on top of the deck. This process can then of course be repeated ad infinitum or are shown card can then be revealed at a time in any way that the performer wishes.
