How Atomic Bomb Works? (3D Animation)
In this video, we will look at how an atomic bomb works, specifically Little Boy which was dropped in Hiroshima Japan on August 6, 1945. Little Boy is a gun-type fission weapon developed in the mid-1940s and was one of three bombs developed during the Manhattan Project having the code name Trinity. Little Boy was the second most powerful bomb after Fat Man among the three bombs. The Little Boy was the first atomic bomb to be used in wars. It was detonated in Hiroshima, Japan on August 6, 1945, at 8:15 AM. It was dropped from a B-29 plane, named after the pilot's mother Enola Gay from 31,000 feet. The bomb exploded about 1,500 feet above the city with a force of 15,000 tons of TNT causing 70,000 deaths instantly and about 100,000 deaths by the end of 1945.
The little boy bomb that was detonated in Hiroshima damaged up to 2.1 miles in diameter with 1 mile in diameter having been destroyed where the fireball was formed. Within a fraction of a second of the detonation, the ground-level temperature exceeded 7,000 °C or 12,600 °F and a powerful blast wave scoured the landscape. Out of a population of 343,000 inhabitants, some 70,000 people were killed instantly. Although less than 2 percent of the uranium-235 contained in Little Boy had achieved fission, the bomb was horrifying in its destructive power.
