- hmartiniano 2mo agoSomeone please nominate this for the Ig Nobel Prize.
- dgrin91 2mo agoI'm not sure if you were joking but they actually won it this year
- hmartiniano 2mo agoThanks, I wasn't aware of this. It was jut the first thing that popped into my mind when I read the title. I wasn't the only one, apparently :)
- slicktux 2mo agoWhen I use a urinal I do not aim directly on front but instead to the curved lower part. That helps guide my urine down; virtually eliminating all splash back!
- jimmaswell 2mo agoother people are just standing there shooting head-on?
- delichon 2mo agoMaybe males are marginally better at geometry due to this additional hands on experience with angles and parabolas. We practice and study ballistic trajectories daily.
- 0cf8612b2e1e 2mo agoI cannot say I have a big problem with urinal design, but I do take significant issue with standard installation practices. I am an average height dude, yet many urinals seem to be installed as if the intended audience are all basketball players. Far too high such that I can imagine a decent chunk of users might have to aim up and or stand on their toes.
- jimmaswell 2mo agoHow tall are you and where do you live? I'm dead-on average US male height (5'9") and I've never experienced this.

- 2PqboPPmKegvanx 2mo ago>I do take significant issue with standard installation practices I just don't understand why there is no middle option. Either on the ground for a 6 year old or set up for a 2m+ man.
- jimmaswell 2mo agoThis is perplexing because I've been all over the country, coast to coast and north to south and to Canada, and never encountered this despite being shorter than the person you're responding to (who is actually well above-average height..)
- yummypaint 2mo agoI was expecting you to say the opposite thing! In North Carolina they are so low that the stream angle ends up much steeper than intended, like trying to use a boy's urinal. I'm tall, but still fit normally in cars etc. There should really be more variation in mounting height, or bring back those tall ones that work universally. I guess it's cheaper to make them small but mounting the flush handle below penis height is asking for trouble.

I do recall there was another story of putting a "target" at the right place in existing urinals significantly improved cleanliness
