re: Which side of the urinal do you pick?

I go sit in the stall to pee

I get as close as I can without touching and aim at an angle as equal as possible to that of the urinal's surface. It seems straight forward, but there is actual science behind it... it's called the "Plateau-Rayleigh instability."

In analyzing their results, the researchers found that sitting on a toilet, as most men well know, results in the least amount of splash-back (the contact point is much closer). They also discovered something likely few men have considered—that urine follows what is known as the Plateau-Rayleigh instability—where a pee stream breaks up into drops before striking something else. That's the worst thing that can happen, the team reports, because each drop creates splash-back. To avoid that, men should stand as close to the urinal as possible they advise. Also helpful is directing the stream to hit the back of the urinal at a downward angle. That creates less splash-back and the drops that do bounce, head downwards into the urinal drain. Conversely, to prevent messing one's trousers (or angering neighbors) they suggest men not spray directly into the urinal or into the pool that forms at the bottom of the urinal, both cause a lot of splash-back.

There's definitely a compromise here between closeness and angle. The closer you are, the closer to an equal angle you can get to the surface of the urinal.

Middle, every time. Makes the other guys on the end uncomfortable.

And this may be the worst thread in the history of Tigerdroppings. I'm ashamed of myself for it.

Eh, don't sell yourself short. There's this one guy names Rebloke. yea...

Cant believe nobody said sink yet

I move it all around randomly to keep the urinal demons off-kilter so they can’t get me.
