A 1/2" diameter, threaded steel nut and a bolt is displayed. The nut is unthreaded from the bolt. Both nut and bolt are fully examined. The nut is then VISIBLY threaded fully onto bolt. This threading process takes about 20 seconds. There is NO DOUBT that the nut is FULLY THREADED onto bolt. The performer closes his fist around threaded nut and bolt. In less than ONE SECOND the nut is free from the bolt! Again both nut and bolt are fully examined. Bolt is 2" long and 1/2" diameter. Close up visual magic that is easy to do.
