Thermite Grenade Cuts Through Steel

Demonstration of a thermite grenade manufactured by ALS Technologies, Inc., a Bull Shoals, AR.-based less lethal and defense logistics company. Thermite is a pyrotechnic composition of a metal powder and a metal oxide that produces an exothermic oxidation-reduction reaction known as a thermite reaction. If aluminum is the reducing agent it is called an aluminothermic reaction. Most varieties are not explosive, but can create short bursts of extremely high temperatures focused on a very small area for a short period of time. The thermite is simply a mixture of metal, often called the "fuel" and an oxidizer. Its form of action is thought very similar to other fuel-oxidizer mixtures like black powder.
