Die Glocke (“The Bell”) was a purported top secret Nazi scientific technological device, secret weapon, or Wunderwaffe.
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, Die Glocke is described as being a device “made out of a hard, heavy metal” approximately 9 feet wide and 12 to 15 feet high having a shape similar to that of a large bell.
This device ostensibly contained two counter-rotating cylinders which would be “filled with a mercury-like substance, violet in color.
This metallic liquid was code-named “Xerum 525” and was otherwise cautiously “stored in a tall thin thermos flask a meter high encased in lead”.
Additional substances said to be employed in the experiments, referred to as Leichtmetall (light metal), “included thorium and beryllium peroxides”.
Die Glocke was described as emitting strong radiation when activated, an effect that supposedly led to the death of several unnamed scientists and various plant and animal test subjects.
Based upon certain external indications, speculation continues that the ruins of a metal framework in the vicinity of the Wenceslas mine (aesthetically dubbed “The Henge”) may have once served as the test rig for an experiment in “anti-gravity propulsion” generated with Die Glocke.
