3 The Manhattan Project A race began in 1940 between the Germans and the Allies to complete the first atomic bomb. The Americans recruit a group of scientists from around the world. This group includes Albert Einstein It is called the Manhattan Project because most of the initial research was done at Columbia University in Manhattan The project cost over $2 Billion

4 The Manhattan Project The first Atomic Bomb is detonated on July 16, 1945 on an Airforce base in New Mexico It was placed on top of a steel tower and watched by scientist from 9km away The explosion came as an intense light flash, a sudden wave of heat, and later a tremendous roar as the shock wave passed and echoed in the valley. A ball of fire rose rapidly, followed by a mushroom cloud extending to 12,200 metres. The bomb generated an explosive power equivalent to 15,000 to 20,000 tons of TNT The tower was completely vaporized and the surrounding desert surface fused to glass for a radius of 800 yards (730 metres)
