Question

As a dude, why does our pee twist once it becomes airborne?

Answer 1

The piss stream has angular velocity as it leaves your urethra. That basically means it is rotating.

Now, since water has high cohesion force, meaning it likes to stick together, that keeps the piss stream twisting after it leaves your urethra instead of flying outward from the center.

If water didn’t have high cohesion, your piss stream would be pretty messy with the same urethra shape.
