This video crushed my expectations

Now imagine your beer can isn't made out of a material which undergoes plastic deformation but instead a material that can only fail by shattering.

Its amazing and terrifying to be able to see what Hank Green meant by "they ceased being biology and rapidly became physics"

I think it is really clever how you created this video about safety, and your instructions for the experiment is a perfect example of complete safety protocols.

Kyle Hill is probably my favorite science teacher since Adam Savage.

I love the barely contained rage you can see behind Kyle's eyes as he describes the incredible amounts of ineptitude that went into allowing something like this to happen.

Still insane to me how Any engineers worked on this. Any engineer with half a brain would know that carbon fibre cannot last many cycles, and also cannot be tested nondestructively, making it one of the absolute worst materials for a deep diving sub.

Mythbusters did an excellent video showing what happens to the human body at extreme depths. They made a cadaver out of pig parts and put it in an old diving suit with a metal diving helmet. When they shut off the equalizing pressure in the suit, the entire cadaver was horrifyingly squeezed up into in the diving helmet. And that was only at around 90 meters, not even 3% of the depth of the Titanic.

I think the most damning indictment of Stockton and Oceangate's hubris is just how short every video explaining what happened is

I remember this simple demonstration from my chemistry teacher back in the 8th grade. We used steel beer cans, because aluminum was not as popular in the Late 70s . Still the pop sound is a strong reminder of how pressure is all around us.

If that soda can was Titan, the beer can was Pisces III. The latter was a DSV that got stranded on the bottom of the sea for a time, but the worry there was running out of oxygen because the main hull held just fine. The crew of two later got rescued on the verge of running out of air.

It's amazing how you can actually see the water level get lower when the can sucks all the liquid in, all in less than a second, you gotta love physics

The experiment Kyle demonstrated is far more effective at explaining the catastrophic failure of the sub than any CGI recreation of the disaster. The implosion of Titan was a tragedy that could have been avoided had the physics been respected when designing the vessel.

I’ve been trying to imagine what this would’ve looked like from outside the sub. Since carbon fiber shatters, the implosion must’ve been like a reverse frag grenade. 🤯

The Artemis Fowl books had a similar metaphor. "Like a soda can in the hands of a giant who was immensely strong and didn't like soda cans."

The thing I found quite interesting about the sub disaster was the fact the time taken for the sub to implode was less time that it takes for an electrical impulse to reach the brain. Meaning the people that died could well have had the fastest and most 'painless' death in history.

the reaction at

There's an episode of Behind the Bastards about Stockton Rush. I cannot stress enough how often this man, in interviews and on camera said "ahhhh, it's probably not that bad. Safety shmafety". He was quite literally asking for it, and was going to get someone killed eventually.

So Kyle, when are we going to get a mini episode about why water can instantly start and stop boiling? I know you stopped yourself b/c you were starting down a rabbit hole, but I wanna see where in Wonderland that hole comes out.

This explanation AND the experiment was amazing to show how disastrous that submarine was.
