Flexible Mirror by Ickle Pickle (M11)

A solid plexi-glass mirror is displayed inside a solid frame. The frame is placed into a cloth bag and the bag is zipped shut. The Magician then thrusts a solid hat pin through the center of the frame apparently penetrating the mirror as well. He then proceeds to bend the frame until it is folded in half! The bag is then opened, the frame is removed, and the mirror is left unharmed.
