Die Glocke Die Glocke ( , German for " The Bell " ) was a purported top secret Nazi scientific technological device , secret weapon , or " Wunderwaffe " . First described by Polish journalist and author Igor Witkowski in " Prawda o Wunderwaffe " ( 2000 ) , it was later popularized by military journalist and author Nick Cook as well as by writers such as Joseph P . Farrell and others who associate it with Nazi occultism and antigravity or free energy research . According to Patrick Kiger writing in " National Geographic " magazine , " Die Glocke " has become a " popular subject of speculation " and a following similar to science fiction fandom exists around it and other alleged Nazi " miracle weapons " or " Wunderwaffen " . Mainstream reviewers such as former aerospace scientist David Myhra express skepticism that such a device ever actually existed . History . Discussion of " Die Glocke " originated in the works of Igor Witkowski . His 2000 Polish language book " Prawda O Wunderwaffe " ( " The Truth About The Wonder Weapon " , reprinted in German as " Die Wahrheit über die Wunderwaffe " ) , refers to it as " The Nazi - Bell " . Witkowski wrote that he first discovered the existence of " Die Glocke " by reading transcripts from an interrogation of former Nazi SS Officer Jakob Sporrenberg . According to Witkowski , he was shown the allegedly classified transcripts in August 1997 by an unnamed Polish intelligence contact who said he had access to Polish government documents regarding Nazi secret weapons . Witkowski maintains that he was only allowed to transcribe the documents and was not allowed to make any copies . Although no evidence of the veracity of Witkowski ' s statements have been produced , they reached a wider audience when they were retold by British author Nick Cook , who added his own views to Witkowski ' s statements in " The Hunt for Zero Point " . Description . 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 nine feet wide and 12 to 15 feet high , having a shape similar to that of a large bell . According to Cook , 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 " . Cook describes " Die Glocke " 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 , Witkowski states that the ruins of a metal framework in the vicinity of the Wenceslas mine ( aesthetically dubbed " The Henge " ) , may have once served as a test rig for an experiment in " anti - gravity propulsion " generated with " Die Glocke " ; others , however , dismiss the derelict structure as simply being a conventional industrial cooling tower . Supposed whereabouts . Witkowski ' s statements along with Cook ' s views prompted further conjecture about the device from various American authors , including Joseph P . Farrell , Jim Marrs , and Henry Stevens . Farrell says that the device was considered so important to the Nazis that they killed 60 scientists that worked on the project and buried them in a mass grave . In his book , " Hitler ' s Suppressed and Still - Secret Weapons , Science and Technology " ( 2007 ) , Stevens states that " Die Glocke " contained red mercury and describes stories alleging that a concave mirror on top of the device provided the ability to see " images from the past " during its operation . Witkowski stated that " Die Glocke " ended up in a " Nazi - friendly South American country " . Cook , on the other hand , states that it was moved to the United States as part of a deal made with SS General Hans Kammler . Farrell stated that it was recovered as part of the Kecksburg UFO incident . This last theory was dramatized in 2009 by The Discovery Channel and again in 2011 by The History Channel ' s " Ancient Aliens " series . In popular culture . The books " Black Order " by James Rollins , 2005 , " Swastika " by Michael Slade , 2005 , " The Shadow Project " by Scott Mariani , 2010 , and " Echo of the Reich " by James Becker , 2012 , have " Die Glocke " as their central theme . The horror / action movie " Outpost " , in which a group of mercenaries are hired to retrieve " The Bell " from an abandoned bunker . The song " Die Glocke " by Cage , 2009 , in the album Science of Annihilation also deals with this subject . " Die Glocke " also makes an appearance in several video games , most notably the series " Call of Duty . " Further reading . In chronological order :
