Pee stream physics

[HitEmAll 1,068]

 

I really like pee and I also like physics.. I found this video quite interesting. It is a somewhat absurd idea to try to create nice peestream-like shaped streams without actually peeing.. 😅

And the video raises important questions, e.g.

1. most importantly, what shape is your pee stream (and who can do the spiral stream?)

2. here we have of course much more possibilities than on youtube.. 😉 can we beat the pictures / videos of artificial pee streams with real pee streams? 🤔

This is something that fascinates me about men peeing. Someone pointed it out to me and I can't quite look at any of the pictures/videos here without seeing it lol. It's so pretty to me! 

One of my favorite videos shows the dude has a long twist at the beginning of his stream and then nothing after, and in others he has several more twists! I fucking love it and I don't know why lol

I posted a similar thread a while back called, "Twists in your pee stream".  Maybe the admins can merge the topics.

 

I too like twists in pee streams.

I like physics too--and of course pee as well. I just looked at mine--when it's going full speed it only has one 90 degree rotation that's "clean and crisp", by the second one it's already starting to break up into droplets. It also does seem to have a bit of an actual helical twist to it. As the flow rate slows down by the end, at least two if not three 90 degree switches become visible for a short while as each segment gets shorter.

I looked some at female pee streams in photos. It seems that there is a lot more variability in women (like there is in all aspects of peeing!), depending on how the labia direct the stream. When they form a neat "slit", the phenomenon that makes the "chain" shape can be even much more pronounced than for men because the length and width are even more different. There are cases where a "blade" of pee very obviously rotates 90 degrees shortly after exiting, such that it fans out sideways toward the legs rather than back to front. However, in women it's more likely that the stream breaks into a messy stream of drops as it exits, in which case no "chain" shape is visible. And when the stream directly exits from the urethra without hitting anything, it's too round to make much of a chain.

Does a double stream makes a double chain shape?
