Physics Solves One of Man’s Biggest Problems: Urinal Splashing

Like my dog, we view the world as our urinal.

How about that galvanized 1/2 circle trough at the ball field?

Put Jane’s sticker over on the edge, not the middle.

[sasquatch]

Depends.

[dforest]

Yeah, but there are no Tampon dispensers beside bridges.

Did any of our tax dollars sent to Canada pay for this study?

Who cares? I want urinal cakes with Adam Schiff’s and Hillary Clinton’s face on them.

Always happy (even in February) walk outside and pee on my property and eliminate the splash issues. One of the parts of home ownership that I truly enjoy.

Yep, not a new design and it's all about the impact angle. 90 degrees or close to it is gonna splash. Slight angles won't. Simple stuff learned easily by washing a car, especially at a self serve car wash with pressure washer jet spray or actual pressure washer or rinsing dishes or.....

Meanwhile, an old design. They had these at the town fair where I grew up. Look only at the wall, even if talking, was instruction given by fathers.

Also allows hosing the floor and provides a drain.

A bar in Boulder (the Sink) used to fill the target area with crushed ice.

How many times have I wondered , on standing before some public restroom urinal , if some guys idea of marksmanship isn’t in the same ZIP code is good enough.

It isn’t the angle ... it is the “shooter”.

[FamiliarFace]

Maybe men’s room should just have silk trees or bushes in them. Have a trough on the ground that drains with a little water running afterward to clean it up.

[9YearLurker]

Anyone who has poured liquid into a glass (such as beer in a mug, especially), knows this.

[sasquatch]

Looks like the old Stanford stadium. Some places used to hang the daily newspaper on the wall for entertainment.

And what do you do for a living?

I analyze toilet designs to determine critical angles to reduce urine backsplash. We're making tremendous strides in our research!

or we could all just lift our leg

“Like dogs being able to avoid their own spray, now humans can benefit from the same physics principles, through intentional design rather than evolutionary coincidence.”

Really? Show me the results of a dog standing up at a urinal peeing, for comparison.

Feminists despise the urinal, yet for many years the feminists researched hard to design one for women, for equality, since then they have concentrated on eliminating them from the military and American life, and have been pretty effective at it.

During the 1960s Cornell did an elaborate study on the American bathroom and recommended urinals in homes, which would be smart and save much water, yet as in so many things, America was driven in the opposite direction by feminism.
