Магически проникване огледало

A pencil penetrates through a clear glass sheet. The performer displays a clear sheet in a plastic frame. After the frame is examined, two playing cards are placed over the middle of the clear sheet. A pencil is now pushed through the cards, apparently penetrating right through the middle of the plastic sheet. When the frame is now examined, the cards have holes through them, but the clear plastic sheet sandwiched by the cards is entirely intact. And the frame can be handed over for examination. Clear Penetration is a mechanical self working item, easy to do when you follow the instructions enclosed. Excellent value, and a trick ready to use at any time, under any performing conditions.
