Exploding Light Bulb by Elian Agaian & Yigal Mesika

A clear light bulb is removed from a lamp (for example a table light), which has been turned on and off, and can be shown to spectators to be a regular bulb. The performer holds the base of the bulb between his fingers and concentrates on it.

Suddenly and unexpectedly the bulb explodes and shatters into little pieces.
