Destination Unknown( wow ) by Ickle Pickle - Trick

A spectator is told to select a city from a group of 100. He is allowed a totally FREE choice. There are ten cities on each of ten cards. He merely points to the card which has his city on it. He then turns his card over , without seeing the card. He mixes the cards and lays them out on the white side. Once again he finds his city. When he points to the card with his city, you INSTANTLY know which city he selected.
