Open Your Mouth, And You're Dead

We took a can coolie to 110 feet. It was roughly as big around as a pencil at that level.

So these folks are wanting to go to 800 feet? Oh, film it, I'd love to see a body cave in on itself.

like one of those neoprene sleeves that keep your beer cold? Mostly air, right? Well your body is mostly incompressible water. Your lungs, hell yeah, but they're designed to compress, like on and exhale. But I agree with you, that must feel like being crushed.

When you're at depth the air in your lungs is at the same pressure as the surrounding water. If you're breath holding from the surface the air is still pressurised , it just reduces in volume, the risk of narcosis and bends are the same.
It takes time for nitrogen to be absorbed into tissues, just as it takes time for them to be released, the time spent at depth is very small, so the bends are unlikely. I don't rememeber if narcosis is also time related but I rememeber them saying it's something you can get accustomed to, like drinking.

Only the air spaces in the body are subject to volume change, at 300m you lungs would be 1/30 th the size !

I skimmed the article and didn't find any reference to "open your mouth and your dead', maybe it's in the video, but since pressure it equalized it shouldn't matter if you open your mouth.

I got it from the title of the article.

Yeah but they never explain in the article why.

A catchy quote out of context is one thing, a dramatic headline out of nowhere is BS.

I think footfoot has it right.

3foot probably does...Also, I'm guessing you don't read a lot of newspapers.

Dude, the first rule of Freediving is You do not talk about Freediving!

Herbert Nitsch, a 41-year-old Austrian, dove more than 700 feet—
assisted by a watersled on the way down and an air bladder to pull him to the surface
—to claim a new world record for absolute depth.

Thats kinda like cheating to me. Of course I can only hold my breath for about a minute.
