At the peak of the Cold War, the US started detonating atomic bombs in the Nevada desert. Fake homes were built and mannequins were positioned to test what kind of destruction the bombs would cause.
The particular test of the video took place in 1955. Mannequins were arranged near the blast. They were used to see how deadly the blast was from different areas and distances.
The aftermath of the test, one of dozens carried out in the South-West throughout the 1950s, also shows that some people could have escaped from a nuclear attack, as some of the dummies are merely burnt without being utterly destroyed.
But it was not just the dummies who were being tested in the fake village. The government also wanted to find out what effect nuclear weapons would have on the food supply and other vital necessities.
