Came here with the same nitpick. It settles down too slowly. Also takes too long to start moving after changing angle. So it's in this weird spot where it's both more + less reactive than real water.
Funnily this is usually something you need to fix in water simulations like this one since a lot of solutions have artificial too rapid energy loss. So the fact that it acts this way is sign of more mastery rather than less (it’s trivial to reduce energy faster).
What's the point of this comment?
Are you worried that someone wouldn't know that it doesn't look realistic? And might get sick by drinking something with fluid dynamics that resemble the simulation?
I looks like it is more compressible and elastic than normal water which may cause the behaviour shown. If I'm not mistaken normal water is very hard to compress.
The motion doesn't even work running Bromite on Android, presumably because of the fingerprinting protection.
Its crazy how our phones have all these sophisticated sensors, yet they are mostly used for something related to tracking for ads. So much so that I don't notice when its blocked.
It used to be available as standard on both but iOS locked it down after some truly insane demos showing how it could be used for fingerprinting or (IIRC) even detecting what users were typing.
Interesting. Sometimes pockets of not-water (vacuum?) appear in the middle of the liquid. Based on observation of real water, such cavitation would not form in water splashing around in a bucket.
The term bubble implies that the not-water is (mostly) air. But these voids are appearing in the middle of the water, there is nowhere for the air to come in from.

I had seen the one layer before, but they way they get it to go forever and make it work so smoothly by dynamically adjusting the speed is pure genius!
I would like to check later on if the rules for this "cellular automata" (if it is one) are documented and the fractal nature naturally concludes from it or whether the fractal was simply manually forced when you zoom a certain level.
Wow, that is so cool! I’ve fiddled with Conways game of life a lot, implementing it recursively in SQLite, various languages, explored variations of it; I knew you could simulate it inside the game, but this is mind blowingly cool! And it’s so smoothly done, it’s like stepping through the looking glass.
This little app makes me feel, perhaps more than I ever have before, that CA might be what's under the hood of the whole universe. (Not a Wolfram fanboy, just reporting on a new sense of awe and mystery!)
the Bell Inequality is one of the things that really puts a damper in that idea. It's like OK everything is local with a speed limit, but there is a little but of superluminal stuff it's just not actually useful in any way except to wet blanket ideas like this.
My dad worked on the Apollo program In The 60s. They were using analog computers to simulate fuel slosh in the tanks. He also had a flight sim display that allegedly could go from space (earth as a circle?) To low level horizon and grid. I never saw either but am about to toss schematics for the later with the rest of his stuff. Personal note - he died in '03 and I'm done hanging on to stuff. :-)
I don't have the domain expertise or interest to know what's important or rare, and I can completely understand not wanting to hang on to it personally any longer, but that sounds like something a lot of people might be interested in, that ought to be exhibited somewhere, if (as it sounds like) it's work-oriented and not too personal.
If you are planning to toss schematics used in the Apollo program, I would love to frame something and put it on the wall. I understand the weight of historically significant junk (and I don't think I would want to have tons of it myself), but that's very different from a piece of engineering history.
I’m sure there are historians or historical societies that would love that stuff. Please don’t trash them. I’d recommend that you go to the AskHistorians subreddit and ask who would want them. I’ve seen people ask similar questions there and they seem to usually find a good home for the stuff. It would just be a little more effort than throwing it away but could mean a lot to future generations of historians.
I sent you an email -- happy to help (virtually) with finding a good home for these. Cleaning out a lost relative's possessions can be hard. I think a lot of other people here might be able to help in some ways too.
I always took water for granted. In my country where I grew up, we had water available to us in the sink 24/7, 365.
Pure, clean. Drinkable.
As I am now traveling the world, I am experiencing places where water is not to be taken for granted. But only in mild ways. Not in actual life-or-death ways. That happens in countries I have not yet visited.
It’s weird. Most of my time at work I deal with pretty mundane things. And if I am thirsty, water is always available.
Water simulations are extra interesting to me now, because I am realising that in the future maybe I can help bring water to places where people are struggling because of unreliable access to water.
I think it would be very nice to be able to help other people on that way.

Could it be that in space or low gravity water behaves more like this?

This is why we can’t have good things.
FYI: you need to run it on your phone with motion and orientation access provided to the app.

In real world it's due to chaos but how is it "simulated" in this simulation?

Please don't trash them, I will take them and pay you for shipping and your time. My email is in my bio.
I understand why you don't want to hang onto them, no judgement.

I should find some time and modernize it with some more features.
