 @b05df304 material density, right? I know it well enough. I just hadn't considered it for this case because it came easy when I used to do it.

 @2dfc6694 Yup in the end its all about density... thats why as a scuba diver when im neutral if i breath in I go up, I exhale I go down.. I dive caves and often control my breath to control my movement.

 @b05df304 oh that sounds like a nice way for finely-tuned control. I wonder if it is as natural as it sounds from the description.

 @2dfc6694 Not natural at all.. new divers take quite a few dives before they get their boyancy control in check... For me as an expiernced diver at the top of the expertise scale, yes its very natural for me and i can do back flips and blow bubble rings, and go through very narrow openings with sharp edges comfortably... but it took many years and many hundreds of dives to get to that point.

Even now when i dont dive for a year I need to spend a little time in a pool or shallow water on my first dive just remembering my skills.. They come back quickly, but they really do take some practice.
