Really stupid science question...

Post by Mr. Coffee »

This is comepletely stupid, but I got to know...


Guys, ever notice that sometime when you take a leak you get bubbles when it hit's the water and sometimes it doesn't? What I mean is when the stream of piss hit's the water sometimes you get something like beer foam forming on the water. Most times you don't though.


What causes that piss foam?

The piss is moving fast enough to bring air down with it. The stream of piss creates air friction and some of the air gets pushed down into the body of water below. At least that's the best explanation I can come up with.

Thanks for asking though, it's an interesting question. :D

Well, if it's like frothy, spongy foam you're either emptying that bladder really fast or.. something's wrong.

A condition like that would probably be the result of a hole in the urinary tract. It is actually possible to get air bubbles in there, this actually happened to someone I know who caught some shrapnel from an IED in Iraq. While he did recover mostly intact, he did have some harrowing moments afterward.

Oh, so it's not from drinking too many carbonated drinks? What a relief. :P

Urine has lower surface tension than water (exact amount depends on diet), adding it vigoriously to water will result in bubbles. The mechanics here should be the same as with soap, just scaled down a bit. Excessively frothy urine might be a sign of jaundice as the bile present will further lower surface tension (one of the tests for jaundice utilizes this property).
Very funny, Scotty. Now beam down my clothes.

Yes. Well, either that or your toilet has one of those soap-freshener things under the rim and leaves some soap in the water after every flush.
