MIND TRIP is a direct double prediction with interesting props and a great theme. Very commercial and totally self-working!
The magician states that he has just returned from a city vacation. He introduces a small metal suit case (about the size of a deck of cards) and a deck of playing cards. He removes the cards from their box and freely shows the faces to be all different and thoroughly mixed. The deck is turned face down as the magician explains that he has written a famous city on the back of each card giving a choice of one of the fifty-two most popular cities in the world to visit.
A spectator selects a face up card which is placed on view while the magician shows some of the other cards and cities that the spectator could have selected. The spectator turns their selected card over to see for the first time which city they chose, Las Vegas. The magician picks up the small suit case and turns it over to reveal a Las Vegas travel label attached to its side! Not only that, the magician explains that whilst in Vegas he picked up a souvenir from one of the casinos. He opens the small case and shows that it contains a single playing card from one of the famous casinos in Vegas, but not just any card, when the card is turned over it is discovered to be identical to the one selected by the spectator!
