Yeah. Reminds me of this underwater pressure awareness training video on youtube from a few years ago: https://www.youtube.com/watch?v=PXgKxWlTt8A (if you're squeemish, don't click that link)
Industrial divers / welders / etc get all kinds of training to avoid that stuff, for good reason.
I'm sure they never imagined this video being paired with an incident like this but wow, their joyful and excited reactions (with no context of the lead up to this experiment) feels really morbid/sick. I realize they were trying to prove a myth and it worked, but still found it unsettling.
