Cliff Townsend corks for cork penetration trick

British magician Cliff Townsend, one time President of the British Ring of the International Brotherhood of Magicians, had these corks made up as a novelty give away. Each cork has his name printed on it. Two corks are needed for a baffling stunt. The magician places one cork in the fork between thumb and first finger of their left hand, and the second cork in the same position of their right hand. The magician moves their hands together and then separates them, showing that they now hold each cork between thumb and finger, but this time the cork that was in the left hand is now in the right hand and visa versa. It looks so easy but when someone else tries, they find that the corks lock together and it is impossible to separate their hands.
