The best cards to use for this effect are the magicians favourite Bicycle brand of playing cards. However if you do not have this type any playing cards will do.Take any ordinary playing card and one of the jokers from the pack.Take any ordinary playing card and one of the jokers from the pack.Fold the joker card in two, length ways back to back then place some glue or double sided sticky tape along one side, on the face of the joker. Press the two together exactly.Carefully stick the face of the joker to the back of the regular playing card(See pic 1).From casual holding and showing the card(s) front and back (pinching the card(s) together on the open side) the card(s) looks normal.However at any time you can unfold the back of the joker card to act as a stand for the card to stand up and support an object such as a glass(See pic 2).The glass can be empty but preferably contain liquid. You will have to experiment with different glasses and the amount of liquid to put in as the playing card(s) can only take so much weight. But as you can see from(pic 2)the card(s) can hold quite a lot of weight!To set the trick up place the prepared card into the middle of the deck and get a glass with some coloured liquid in. The liquid in the glass makes the effect that much more impressive as well as adding cover so the spectator can not see the other card through the glass!To force the gaffed double card onto the spectator you can either casually shuffle the deck then look as if you are randomly taking any card from it to perform the trick but in fact choose the prepared card.However if you are a more experienced magician you can use the riffle force to cut to the prepared card.

The riffle force basically involves you holding the deck in one hand and riffling though the cards until a spectator says"Stop"Because the prepared card is in fact a double card the riffling will naturally stop at that card. All you have to do is time it right, so when the spectator says"Stop", you stop at the prepared card.This does take practice, but is well worth incorporating into the routine if you can master it!
