Why men splash (it's physics, not you)

Fastest draw in the bathroom.

Height is the problem

Standing, the stream falls about two feet before it hits anything. It breaks into droplets on the way down, and droplets bounce.

Angle makes it worse

Hitting water or porcelain straight on sends droplets back up and out, often past the rim. A shallow angle against the side of the bowl reduces this a lot.

The morning angle

In the morning, the stream often points forward instead of down, which makes a clean angle almost impossible without leaning over the bowl.

The fix

Shorten the fall and control the angle. Sitting down shortens the fall. A funnel like the Pee Shooter slows the stream in a small splash chamber and points it down into the bowl, so it never gets a chance to bounce.
