Originated by master machinist Carl Brema, this has become a staple in the close-up arsenal of many professional performers. A brass nut is handed for inspection along with a length of cord. The spectator is asked to thread the nut on the cord, and then to hold both ends of the cord. It will now be seen that it would be impossible to remove the nut without letting go of either end, but that is just what the performer does! This is the finest set made. Can be examined before and after the effect. Great for table-hopping or for any intimate magic session.
