Sadly, there is no known structure tall enough for me to pee off of without my penis making contact with the ground due to its extreme length.

StillFullyTerrible posted:if they're on a surface like concrete, the impact from a sufficiently large amount of water can very easily smash their head into the ground hard enough to kill them Yeah. Water from a lower height would actually be more dangerous, as it would still be a coherent mass that could slam you. Any amount of water dropped from skyscraper height would just atomize and be a nice rainshower by the time it got to the ground.

StillFullyTerrible posted:the surface tension of the water acting as a solid for an instant is what kills you when you drop onto it from a great height It's got nothing to do with the surface tension, it's about the fact that water really doesn't like to compress, and that when you hit it hard enough it will try to compress because it can't get out of your way fast enough. Same deal as re-entry into the atmosphere. It's not friction that burns things up, it's the air compressing in front of the object hitting the atmosphere at several kilometers per second.

So the air resistance on the way down when dropping water from a height starts the compression before it gets to my head? Whereas me jumping from a bridge doesn’t turn me into a shower so I hit the water like the tubby gently caress I am and explode against the un-compressed surface?

We know that humans pee for 21 seconds, and we can probably find out the average volume. What we need now is the speed water needs to penetrate skin and/or break bone, and we can go backwards and calculate how small the urethra must be to unload the volume at the given speed within the 21 seconds.

Or, given a fixed urethra dimension, the bladder volume which would result in said velocity once expelled within 21s

The normal psi of a urine stream is about 0.5 and a water jet cutter runs about 90,000 psi. So if you want to kill someone with your piss laser you'd need to have roughly a 0.75mm urethra (average is about 9mm) and ureter smooth muscle contractions that have the force equivalent of being able to lift 600 tons in order to still only have an effective killing range of about 6". Clearly the superior killing piss is the wide bore.

RandomFerret posted:This is very concerning Keep in mind the pp opening is a tapered end so pee doesn't dribble out, but in stages the urethra runs from 15mm at the bladder to 4-9mm for the rest of the trip then there's a "nozzle" at the urethral opening about 2-3mm. A theoretical small bore piss laser would require a 0.75mm bore or smaller for the urethra with a larger bore at the bladder which would ramp up the enormous 600 MegaPascal forces required to cut through meat with a piss beam without abrasives.
