SS General Hans Kammler and the Nazi Bell

Die Glocke (German: [diː ˈɡlɔkə], “The Bell”) was Allegedly an experiment carried out by Third Reich scientists working for the SS in a German facility known as Der Riese (“The Giant”) near the Wenceslaus mine and close to the Czech border. It was given the priority classification “Kriegsentscheidend” (decisive for the outcome of the war) the highest known category of secrecy and funding priority known in the Third Reich. No other known project had this high of the classification.

It is unclear to this day exactly what the Bell Experiments were and what the goal truly was.
