this video shows the power and the impact of a atomic bomb.1. All the atomic bomb tests you see in this video were conducted after the second world war, it was part of a series of tests called the Crossroad project. Oh and f.y.i when the u.s launched the first atomic bomb on Japan, they didn`t surrender until they launched another one two days after sometime in April of 1945. These tests lead to the type of bomb that we know today, the ``nuclear`` bomb.
