An '''explosive material''', or '''explosive''', is a substance which can produce an burst of [[heat]] and gas when [[heat]], [[electricity]] or pressure is applied to it. Explosive material is highly combustible--lower explosives will deflagrate, but high explosives instantly detonate. This creates a shortwave of heat and gas, which gives the material its destructive power.
