A spectator selects, signs and returns a card to the deck.
The deck is then shuffled and the card that they signed, sticks to the
ceiling while the others fall.
You will need a pen, cards and a piece of magicians wax or sticky tape that
has been rolled in a loop with the sticky side facing out. ( This should be
looped around your finger or under the table)
Have the spectator choose a card which is then, using your own favourite
method, returned to the deck and shuffled to the top.
With the spectators card face down on top of the pack, you can either slip
the double sided sticky tape off your finger and on to the back of their
card or stick a small piece of magicians wax to it.
Then toss the pack hard at the ceiling, keeping it parallel. The spectators
card should stick and the rest of the pack will fall.
This trick is very impressive. It has been performed in different versions
by David Blaine and Michael Ammar.
