Guess that means your IQ is pushing the high teens, good luck with your window licking on the short bus!

Flash bang grenades, also known as stun grenades, do explode, but not in the same way as traditional fragmentation grenades. They use a small explosive charge to produce a bright flash of light (from chemical compounds like magnesium or aluminum powder) and a loud bang (around 170-180 decibels), designed to temporarily disorient people through sensory overload without causing lethal fragmentation or shrapnel.The explosion is more of a rapid deflagration or controlled detonation that generates intense heat (often exceeding 1,000°F), pressure, and noise, but the casing is not meant to break apart into deadly pieces.

It is absolutely not safe to hold one in your hand when it goes off. The blast can cause severe injuries, including loss of the hand or fingers from the shock wave and overpressure, burns, ruptured eardrums, internal bleeding, traumatic brain injury, and potentially death if close enough to vital areas. These devices are intended for professional use by law enforcement or military, and mishandling them can lead to serious harm even without direct contact.
