During [[World War II]], the German [[Nazi party]] used Zyklon B to kill millions of people throughout the holocaust.  As victims arrived at the death camps, they were divided in two: those fit for work, usually young to middle aged men, or possessed a special skill needed in the camp, and the remainder sent for delousing in the showers.  The “showers” was actually a sealed room in which Zyklon B was dropped through a hole in the ceiling.  The cyanide-based vapors would kill the entire room within minutes.
