A spectator chooses two cards that are then used as "doors" to close the cabinet or tunnel with faces towards the inside. You then show the spectators two blank silks and with the help of a magic wand (not included) you push the silk through the holes at the ends of the cabinet. Of course they come out the other end as blank as they were before. After this demonstration you now push one blank silk at a time through the cabinet with the wand and the magic happens. When the silks come out the other side they have the selected cards printed on them! You then remove the cards from the openings and they are now blank and the cabinet is empty!
