THE ATOM BOMB: How does it work?
Many people know what the atom bomb is and what it does, but do they know how? The first Atomic explosion was on July 16, 1945 during a test called Trinity in New Mexico. The bomb is detonated by a molecular chain reaction called fission. Fission occurs when neutrons are fired at closely packed atoms that have lots of uranium. The nuclei break up into littler nuclei which hit other nuclei. By breaking down and releasing the nuclei itself the Atom Bomb releases a blast a billion times stronger than TNT. Although many Atom Bombs were detonated, only 2 were used in war. They were both used by the U.S against Japan.
