Norway’s Finn Jon (Finn Hauger) invented this clever idea c. 1964 and about a year later Anverdi created a beautiful stage size version in plexiglass and created some new routines with the device too.
Performed correctly it is a real beauty and everything can be given to the spectator to examine, they will find nothing.
Anverdi created at least two versions of this item: this one with a blue ring and wider bolts and the earlier version with a red ring and thinner bolts. This is the nicest version he created. Some came with plexiglass boxes and others without. This version had a beautiful wooden box custom built for the effect and it works perfectly.
When performing this effect I prefer to be as hands off as possible and that is what I hope to display in the Speed Demo.
This really is a beautiful effect and one of Anverdi’s signature pieces.
