A Manhole Cover Is Possibly The Fastest Man-Made Object Ever

Question (That you probably have): Why is it possibly the fastest man-made object? Answer: 3 Words. Nuclear. Testing. Bunker. Long story short, an extremely powerful nuclear blast from an underground bunker, caused the 4-inch thick steel manhole cover to be blown so fast off the bunker, that it was caught merely on a single frame of a high-speed camera. After calculations were done, it was concluded that the manhole cover was moving at 45 miles per SECOND. That’s approximately 150’000 MPH, effectively blowing the previous record out of the water.
