During the 40’s and 50’s the USA conducted several tests involving nuclear bombs, this film clip is about "Operation Teapot

1955 – Nevada Proving Ground

Teapot was authorized by President Eisenhower on 30 August 1954. This series of fourteen shots proof tested a broad variety of fission devices with low to moderate yields. As a group these devices combined several innovations – some previously tested, some introduced during this test series – to create a new pattern of fission device that would dominate the design of all later weapons. These devices used new compact, efficient, light weight spherical implosion systems; beryllium tampers; hollow cores; deuterium-tritium boosting; and the use of neutron pulse tubes as initiators to create light, compact, efficient, and reliable fission explosive systems.
