This is a very effective penetration of SOLID THROUGH SOLID.

The performer displays a small wooden box slotted on top and bottom through which a coin can pass.
A glass sheet is placed inside the box, so that it obstructs the slots, filling up the entire inside of the box. There seems to be no way now for the coin to go through the slot, unless it goes through the solid glass sheet. Yet the performer does just that – passing the solid coin right through the piece of Glass.

We supply you with the special mechanical box and the glass (actually more durable perspex) sheet.
You can use any coin, preferably a large one of the large old one rupee, old English Penny, or half dollar size.
This is a deluxe model, crafted in solid wood, polished, with brass trimmings. A quality prop for your act or your collection.
