The performer displays a solid die, and a box with two compartments, and doors to each compartment. The die is placed in one compartment, and the doors closed. The box is tilted, and your audience hear the die slide from one side to the other. So they are not impressed when you open the door to show the die has vanished. They ask you to open the other door.
You tilt the box again and open the door. They heard the die again, and even those that missed it the first time are now convinced they have caught you out. Repeat a few more times, milking it for what ever it’s worth.
Finally open both doors, to show die has indeed vanished, and reproduce it from a hat or container.
This prop is made entirely of perspex, more durable than painted wood with colours that will never scratch off, like paint.
The sliding noise feature is very audible, and you have all the advantages of the regular prop, at a very affordable price. a professional prop with a die measuring 10x10x10 cm !
