Big Beef Burritos Supreme When your bones get weak enough, air pressure will do this to you too. Or just take a deep breath and step outside the submarine.
Feyd okay I give. somebody explain what they did to make this happen at 1 atmosphere.
Billy the Poet Shipping vacuum from the mines in Bavaria.
RockBolt Inside the tank was superheated air, and the tank was left sealed as it cooled to ambient air temperature. As pressure * volume = temperature * gas constant, a constant volume and substantially lower temp = proportionally lower pressure. That pressure inside gets low enough that atmospheric pressure outside is enough of a differential to crush anything like a beer can
Spastic Avenger I think its also because the tank is designed to have pressure acting outwardly and not inwardly.
also KANEDAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Jefka You can see a hose attached, so I'm not sure it's just Joule-Thompson effect cooling.
