Die Glocke (German for "The Bell") is a legendary device attributed to the Nazis during the endstages of World War II and has become infamous amongst fringe scientists and conspiracy theorists who believed it was a type of alien weapon either devised by Nazi scientists or by aliens friendly to the Third Reich. The device was also discussed in the controversial "Ancient Aliens" television series on History Channel, which suggested it was used at least once and that some Nazis may still exist in other time-lines and/or other worlds.
