BLINK by Mark Mason

A card is selected and returned to the deck, the magician claims he will find the card. You look through the deck and remove one card and place it onto the face of the deck. The spectator claims this is the wrong card. You now slowly wave the deck up and down. The card VISUALLY CHANGES into the selection. No covering the deck with your hands or a silk etc the card is in full view the entire time. The selection is removed and shown on both sides. You need to see it to believe it. BLINK IS AMAZING.
