The effect will happen in moments. The mystery will last forever. 

As seen performed on Criss Angel's TV show.

Effect

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 shutters into little pieces.
