Cubone posted:of course it does, matter is leaving your body It will definitely reduce your mass, but might not reduce your volume, and it is the volume that causes the displacement of water. When your bladder expands to full it might simply compress the surrounding viscera/muscles/ interstitial tissue/whatever rather than expanding your waist outwards slightly, such that your external measurements do not change when you then release your bladder. Your water balloon in a pool example works because releasing liquid from a balloon changes the dimensions of the balloon, reducing its volume. But it wouldn't work the same if it was a rigid container that doesn't difform with the release of its contents. But maybe a particularly full bladder does expand the waist outwards. I feel like it might vary by body composition, but it definitely doesn't increase the volume of the body by the full volume of the urine. Average bladder capacity is around 300-400ml, but you certainly aren't losing and gaining a coke can sized growth to your waist between pisses.

gary oldmans diary posted:the only parts of you that are really compressible are your lungs and look at your body when you breathe. air is far less dense than urine and your innards move to accomodate it with every breath Maybe compress isn't the correct word but there are plenty of things that are elastic and expand, contract or otherwise reposition slightly without change to external body dimensions, with the abdomen in particular having some degree of squishiness and cavities to fill. If I tighten my abdominal muscles and suck my stomach in as hard as I can I will be significantly reducing the size of my abdomen and the amount of space occupied by the organs therein, and that reduction doesn't require making GBS threads out an organ or ballooning out above or below the sucked in gut, meaning things are being "compressed". Lungs are a unique situation specifically because of air being less dense, therefore requiring both a huge volume of intake to get sufficient oxygen and an intake method dependent on negative pressure (so having a greater need for expanding space).
