This video demonstrates a high-risk experiment where an M67 fragmentation grenade is subjected to extreme heat within an oven, ignited by a Pulsefire flamethrower. The footage, presented by Edwin Sarkissian, shows the grenade detonating due to cook-off, destroying the oven and scattering debris. It highlights the critical importance of understanding explosive behavior under thermal stress and maintaining safe operational distances.

Quick Summary

Exposing an M67 fragmentation grenade to extreme heat, as demonstrated with a Pulsefire flamethrower inside an oven, can cause its pyrotechnic fuse to 'cook off.' This leads to a premature and violent detonation, destroying the container and scattering dangerous shrapnel. Maintaining significant safety distances is paramount when dealing with such explosive reactions.

Frequently Asked Questions

What happens when a grenade is thrown into a fire?

When an M67 fragmentation grenade is exposed to extreme heat, its pyrotechnic delay fuse can 'cook off,' causing it to detonate prematurely. This experiment shows a grenade inside an oven ignited by a flamethrower detonating violently, destroying the oven and scattering debris.

How does a Pulsefire flamethrower work?

A Pulsefire flamethrower is a handheld device that uses a fuel mixture, typically gasoline or a gasoline/diesel blend, ignited electrically. It's capable of producing intense flames and heat, as demonstrated in this experiment to heat the grenade.

What are the risks of heating explosive devices?

Heating explosive devices like grenades carries extreme risks. The heat can cause the fuse to detonate unexpectedly (cook-off), resulting in a powerful explosion that can cause severe injury or death from shrapnel and blast waves. Proper safety protocols and distances are crucial.

What is an M67 fragmentation grenade?

The M67 is a U.S. military fragmentation hand grenade. It contains Composition B explosive filler and is designed to detonate via a pyrotechnic delay fuse, scattering lethal fragments over a wide area. Its susceptibility to heat is a critical safety consideration.
