This YouTube video shows a 3D model of Krema II, the main Auschwitz gas chamber where 500,000 Jews were gassed, 2000 at a time, in two years time. More Jews died in the Krema II gas chamber at Auschwitz than all the American soldiers who died in World War II. This video shows in detail how the Jews were gassed and their bodies burned in the ovens. The title of the video is Auschwitz, the Comedy.
