This is based upon Tenyo’s effect created by Kento Wakabayashi called Super Spike (T-140) c. 1989.
It is made of solid aluminum and looks and works perfectly. It is important to notice that although the effect looks similar to Magiro’s Coin and Bolt Mystery the method is quite different.
Effect: A quarter, fits into an aluminum holder, which slides into a case. A bolt is pushed through and locked in place, thereby imprisoning the coin in the case. Before you can say Houdini, the coin melts right through the bolt, and is now free!
