A solid glass marvel seemingly passes through a solid brass bolt which has been threaded into a round brass block.
The bolt is 10 cm (4") by 0.9 cm 3/4"). The brass block is 1 cm (1") diameter, all highly polished.
A nut is threaded on to the bolt and the assembly is held at eye level to the spectators. The marble is rested upon the bolt and slowly sinks through the bolt. The nut is taken off and the bolt un-threaded ready for examination by a spectator.
