    Anyone legitimately curious it’s saying welding fumes are harmful. The thing on the left is a welding stinger for stick welding.

      I’m guessing that the material they’re warning about would be galvanized steel. Apparently the fumes are extraordinarily toxic, and there’s fuck all that can be done once you’ve inhaled it. Also, chemically treated steel/metals can have residue that is toxic once heated to extreme temperatures… and again, little to no treatment once you’re exposed.

        Water pressure crushes a submersible’s hull but not his body when he exits the sub. Makes sense

          You could finger-gun this guy in the back of the head and he’d still go nuh-uh, you didn’t get me, I teleported.

          Dude is just fully incapable of imagining a situation where he’s fucked. He’s the protagonist of reality. Legitimately thinks he could fall off a skyscraper and land on his feet. Which is a million times less ridiculous than this submarine, where incomprehensible pressures forced the interior contents to the size of a gumball in a matter of microseconds.

          Every human being in that tin can briefly occupied the same cubic inch. You can’t shrug that off. Not even a blue whale is “built different” enough to survive those pressures, let alone the force of having those pressures applied all-at-once. Especially when pV=nRT, meaning the air temperature inside the cabin - and inside its former occupants - was raised several thousand degrees. Not for long, though. That glowing-hot paste of organic matter was immediately slapped against a wall of ice-cold seawater, sluicing it through cracks in the opposite end of the wreckage, leaving a small cloudy region surrounded by pitch darkness.

          To which that guy would say, “I’d have dodged.”
