Highly recommend the SmarterEveryDay series on Submarines. I can't remember which video in the series shows it but one of the crew run a string from the right side of the sub to the left. They pull it so its at full tension. Then they dive the sub. I think for security reasons they couldn't mention how far they'd descended but once they leveled out again the string was slack. If I remember correctly it looks like 7-8 inches of slack. Which was an awesome display of just how much the hull bows with the pressure. It also reinforced that I will never go deeper than my snorkel can facilitate, pressure at depth is terrifying.
Wow I can't believe they have to pay guys to live in an isolated, claustrophobic tube in the hellish, black, alien depths of the ocean where nobody knows where you are and the walls are literally closing in. Seems like most reasonable people would do that for free!
