Why guys pee in an arc?

Guys pee in an arc because of gravity.

Yes, pee takes a parabolic arc, due to gravity.

An interesting question about pee is why is the first part of the pee stream laminar flow that then turns into chaotic flow farther down.

It has to do with surface tension in liquids I imagine.

Here on earth. . . gravity. In the ISS. . . no clue what happens.

Little pee droplets float all over the place getting into the hardware and cause havoc.

Only if "you didn't point the woohoo south" as i heard in a film.

[Noahnoon21]

Because we want to see if we can pee farther than everyone else

[katiesmuff]

Same principle as using a water hose to wash your car or water your lawn. Comes out under pressure then gravity takes over.

Maybe if a man has an upward curve on this penis combined with gravity.

I don't gamble...

[andreasderjuengere]

... because we can :D

You answered your own question

[Alex-Snow]

Gravity and lack of pressure

[Christopherthegreat]

girls do too, at the right angle.

Do you know that?
