To pull tightly on the skin around one testicle and squeeze that testicle up, isolating it. The resulting isolation of one testicle takes on the conspicuous form of a mushroom cloud after an atomic bomb explosion. Performing this trick with both testicles results in the popular "The Brain."

A weapon developed by the Americans during WWII and under research by other countries including Germany. The weapon is classified as either a Gun type or implosion type.

Gun type weapons are unreliable and do not provide a large blast, therefor rendering it obsolete. Though it is easier to make. The process includes accelerating a neutron(s) into a ball of Fissionable material and inducing a nuclear Fission reaction.

Implosion type weapons are in current use, though, not much, they detonate explosives around a ball of Fissionable material and create immense pressure which induces nuclear Fission. They generally have a higher blast effect.

The Atom bomb was deployed twice at Nagasaki and Hiroshima to end WWII. Though, their use is still hotly debated today. Atom bombs have become very obsolete since the development of Hydogen bombs, Cobalt bombs, and then Thermonuclear warheads.
