Explain that the audience is about to experience a demonstration of Deja Vu. Ten cars are counted an removed from the deck. They are alternately placed face up an face down onto the table forming a small pack which is then placed back on the deck. When the deck is spread the audience can see that now all cards are now facing down one again!
In a follow the cars are again mixed alternately face up an down. Spectator is asked to pick any of the face up cards and turn it face own. Packet is then added back to the deck and mixed in. When the deck is now shown only the card selected and turned by the spectator is reversed in the deck.
Easy to do trick. We supply the special cards that make this possible to be shown as a packet trick. If you prefer to do it with a full deck than you need to add a regular Rider back Bicycle deck (not supplied).
Easy to do.
