If you are here asking: "Is this a science meme?"
Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.
Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.
We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.
See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

What if dispenser machines had a pay by volume model? You bring your own thing, they fill it, and charge you by how much you use. Would probably need something added to measure flow and set prices, but it's not like a McDonalds built in the 70s is still using exactly the same machines they were back then.
Gas pump style soda fountains would be absolutely hilarious. Truly the peak of american culture.
This but in Oregon you'd get yelled at for doing it yourself. :p
Edit: Huh, turns out they lifted that ban in 2023 so now people can pump their own gas.
Years ago at Universal for Halloween Horror Nights they used bottom fill beer dispensers. They had a connector on the bottom of the cup so you could grab a cup pop it down on the machine and keep going. Say 15 beers in seconds. The beer fills to the exact height needed with the exact desired foam amount on top. No over poors or needing to have any loss. Time was cut down drastically. The cups had to be expensive, but when your charging $10 for $1 with of product you don't have to worry to much about cup cost I guess. I remember thinking at that moment American Capitalism has peaked haha.
Could just do it by weight. Put vessel under nozzle. Zero scale, and hold till weight determined for sale, hand to customer. Could likely even have software do it.
Measuring by volume dispensed like gas pumps would be less likely to be abused. I can just lift the cup slightly as its filled and pay less.
