How does flash powder work ?
Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly and if confined produces a loud report. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for flashes in photography.
Flash powders even within intended usages often release explosive force of deadly capacity. Nearly all widely used flash-powder mixtures are sensitive to shock, friction and electrostatic-discharge. In certain mixtures it is not uncommon for this sensitivity to spontaneously change over time, or due to change in the environment, or to other unknowable factors in either the original manufacturing, or in real-world storage.
