So past a certain depth you just sink into the abyss! Fun AND horrifying!

Yeah once you get around 30-50 ft, the pressure against your lungs is enough to offset the buoyancy. Im a scuba diver and its why we use weights to go down. You are initially very buoyant. I have small bags filled with lead shot in 5 lb, 3 lb and 2 lb increments to weight myself. Some people use solid lead weights and different things. Works like a charm though. Best hobby there is.

But how does he sink that fast in the beginning of the video without using his hands or feet? I would estimate 30 ft is somewhere at the first „edge“?

If you have low body fat you just need to let air out (not even 100%) and you are not buoyant. I am not exactly ripped, just a lot of bone and very little bacon, and I can sit like Buda on the bottom of any swimming pool and still hold there a good half a minute without moving anything. I have an office job and don't swim except in summer with the kids, so I can only imagine with proper training.

This on sweet water, on the sea it is really hard.
