Just a Second

Two cards are selected from a deck and signed (using stickers on their faces). The deck is cut in two packs, the magician fans them out and each card is lost in each fan. These two packs are given to different spectators to be shuffled. All cards are put together in vertical position in a transparent glass, and the magician, by means of his sense of touch, finds both signed cards instantly, as soon as his fingers contact the deck from above.
