In Response To: Re: relief on the water (Brian Nystrom)

: Derek Hutchinson has a very funny story from his North Sea relating to this.

: The bottom line is that peeing "uphill" any significant distance
: is damn near impossible.

One term for fluid pressure in a standing column of water is "head". The amount of head is measured in the vertical height of the water in the column. A crass joke could be made about too much "fluid pressure in a standing column of water".

I wonder if standing while wearing one strapped around your calf would literally suck it right out of your kidneys!?

Probably the same reason that trying to breathe by suspending one end of a tube above water, and then submerging oneself 4-5' below the water's surface is damn near impossible. SCUBA regulators actually push more air pressure into your lungs so you can breathe normally as the depth increases. When you begin to surface, you are supposed to breathe normally and not hold your breath. If you take a lungful of air at a lower depth (and consequently higher pressure) and rise without exhaling it, it could actually explode your lungs. PV=nRT Good ol' Boyle's law. The temperature and amount of air in your lungs stays constant, but as pressure decreases, volume increases.
