Penetration Frame

A solid plastic glass in a plastic frame is given for examination. Nothing unusual can be detected. A playing card or business card is placed on each side of the frame, underneath the thin strip, so that the circle in the middle is perfectly covered on both sides. The performer now pierces both cards through the glass, with any borrowed pencil. This can be followed by a silk, ribbon or knife. The cards are then removed by the performer and to everyone's amazement, the glass is in perfect condition and the frame can again be given for examination. Includes the instructions and original box. Very good condition.
