In the streets of Hamburg, Germany, a new form of urban deterrent is turning public urination into an instant lesson in cause and effect. Known as “anti-pee paint,” this specialized nano-coating creates a superhydrophobic surface, repelling liquids so completely that anything touching it slides off with remarkable force. The result? Anyone attempting to relieve themselves on a treated wall experiences an immediate and unforgettable splash-back. The technology borrows from nature, mimicking the microscopic structure of a lotus leaf. Tiny ridges and air pockets prevent any liquid from adhering, meaning walls remain clean while offenders get an eye-opening consequence — all without the need for confrontation, fines, or patrols. It’s an ingenious blend of physics and human psychology: the paint doesn’t punish with authority, it punishes with instant feedback. First popularized in Hamburg’s St. Pauli district in 2015, this approach has since been trialed in other cities like London and San Francisco. While the coating is costly, city authorities note significant savings on cleaning and maintenance, and a marked decrease in repeat offenses. Beyond hygiene, it’s a striking example of how urban design and material science can work together to shape behavior. For engineers, urban planners, and city residents, anti-pee paint is both a marvel of nano-engineering and a lesson in poetic justice. The streets stay cleaner, the message is immediate, and the offender leaves with a story they won’t soon forget.
We have them. Its just that a lot of us are such fucking degenerates that we piss and shit on the toilet seats and in the urinals that no one wants to go fucking near them. Others, have are filled with blue lights, so that all the junkies cant see their veins and shoot up somewhere else.
Basically, we cant have nice things because some of us are just utter cunts. Some have been put behind a paywall, but people moaned about that as well. Basically, there are solutions, but nobody wants them because “what about the people who dont have money?”. And the answer “I guess they dont get to shit in the urinals!” is never a welcome one…
In The Netherlands, we don’t have them, but you can piss at most bars and restaurants. Still the drunk guys choose to urinate at the walls, in the plants, in the bicycles, in the stairways of parking lots. It’s gross and annoying.
I’ve heard the blue light thing before, but is it really that much of a thing? When we look for veins, I don’t even see color anymore. It’s tourniquet, squeeze, fondle your armpit, stab you.
The blue light is a thing. And its not limited to toilets in supermarkets and hospitals. Ive seen them under some bridges as well.
The issue though, like you said, is that most can find the vein by touch alone. And others are just so desperate, they try anyway. Giving exactly zero fucks about the blue light. Which has led some to question whether he blue lights are a good thing, or a bad idea thats going to eventually harm someone.
Maybe it’s because it’s still night where I am, maybe it’s because I’m on the spectrum, but those blue lights feel like an assault on my senses. I had to scroll it off my screen to type this because it made my eyes hurt. I can’t imagine having to deal with that every time I have to pee in public.
I also can’t help but wonder where people go to do their makeup. I don’t use makeup, but I often see others using the mirrors to touch up this or that. I can’t imagine blue lights are helpful in that regard.
sure. it’s an assault on neurodivergent neurons, but did you ever consider we could make things worse for someone who’s already at rock bottom? what do you think we’re supposed to do? make narcan readily available and pay social workers enough to where more people are willing to go into the field and take on the mental anguish of trying to make society work? and sure! this course of action would be less expensive than maintaining the torment nexus, but you have to keep in mind, we tried building a different torment nexus that was aesthetically against the torment nexus and ever since building the torment nexus we’ve only been able to understand the world in binaries.
I welcomed it in the sense I just laughed for 20 seconds
