It was a precursor for submersibles like the Bathyscaphe that ventured to depths of 30,000 feet in the Marianas Trench. At that depth, the vessel had to withstand 1.2 metric tons per square centimeter – that is like 1600+ elephants standing on the roof of a small car. If there is not an equal opposing pressure from the inside, the car collapses.
Homes today are under immense pressure. The elephants show up in ...read on
