Story:
The magician explains that each card of a deck has a particular relationship with another card of the deck; this relationship is not just anyone, it is the one that links the twin cards; for example, the 2 of Hearts is linked with the 2 of Diamonds; the 9 of Spades with the 9 of Clubs, etc... A card is chosen by a spectator and is isolated in the case, previously shown empty. A second card is pointed out by the spectator in a very clear way. The two cards are compared: they are the twin cards!
