From a packet of 12 cards, the Magician deals 6 cards to the spectator and keeps 6 for themselves. Both the Spectator and the Magician place their cards behind their backs, mix them up, and remove one card.
Keeping it face down so even they don’t know which card they have chosen, the Magician and spectator exchange cards and place them face up within the packet of cards behind their backs.
When the two packets are brought forward and fanned out, it is seen that both the face-up “chosen” cards are identical.
The spectators start to believe that maybe all the cards are the same! “Well, all of these other cards may be the same,” you say, “but…
You turn over all the other cards to reveal that all the cards are the same but a totally different card!
