that's a pretty good point, it's literally trapped between being a liquid and a gas. If this was BattleBots, they'd let it compete once and then ban it.
"Trapped between liquid and gas" is kind of the opposite of what a supercritical fluid is. It's more that gas and liquid states are "trapped" in a region of phase space, while supercritical fluids exist in the place where the demarcation between the two no longer exists (which is usually a far larger region than where it does).
Aha! But languical constructs allow and do allow hyperboles! So it could be argued that the colleague asked for the minimum allowed by our bindings law!
It relies on differences in surface tension. If a liquid has a lower surface tension (energy) towards one surface than another, you get the typical capillary effect. In the case of water, the water-air energy is lower than the water-<whatever your capillary is made of> energy, so you get a capillary effect.
If water had exactly zero surface tension against every interface,
This was the first thought that came to my mind on seeing this post.
For starters, basicaly most (all?) land based plants are fucked, they can no longer internally hydrate, also water in soil behaves totally differently, so ...yeah.
(oh on that note, snap your fingers and water has 0 surface tension? time for a lot of landslides/sinkholes in humid areas)
Then you've got beings with active circulatory systems, who... may to some extent be able to live, but lots of pulmonary / circulatory problems are gonna happen.
I guess maybe totally waterborne life could survive, maybe... but 0 surface tension of water probably changes how salinity works...
If we want to go to extremes, zero surface tension means no nucleation barrier for critical bubbles. In practice, this implies that liquid water is unstable, and will spontaneously vaporise at all conditions.
Surface tension and reactions are manifestations of the same underlying phenomenon. I’m certain that causing a change in one would also affect the other.
Capillary action doesn’t happen without surface tension, so long stemmed woody plants are out. Iirc, mushrooms were not super common before trees and spread by decomposing them, so those are gone too
It'd evaporate much quicker TBF. Although that also means that the BP would be much lower and tea and coffee wouldn't be a thing and boiling wouldn't be a reliable method of cooking. although on the flip side, you could increase the strength of alcoholic beverages by boiling the water off instead of distilling the alcohol.
Yep. Generally if one property of it was so different, I'd expect many others to be different as a result of that too. So physics and chemistry as we know them (with so many things relying on water) wouldn't exist. And thinking further how life on Earth started off in the water...
This reminds me of the person that suggested in a response to a request for ADHD “life-hacks” where they would wet one of their socks before starting a specific high-importance task and could not take it off until the specified task was completed.
We would not have life! Water is a polar molecule that is very different from most other liquids. Its the specific surface tension properties that help to create life. The reason why we search for planets with water. We've never worked out a way for any life to exists without the amazing H2O.
As an odd thought experiment or are we hoping that the laws of physics might be different there? All water, except brand new in reaction space is almost certainly going to contain dissolved ions
Well I think the idea is more that for some reason water needs to be treated with something that removes surface tension if you want to safely pipe it to people's houses. At least that shouldn't destroy all life.
Yes and no. No surface tension implies vanishing intermolecular forces, so the liquid would not be cohesive and would expand in all directions to the volume of the room... which is pretty much the definition of a gas. Not quite though: supercritical fluids also do this as long as temperature and pressure remain high enough, and are indeed useful in niche applications industrially.
You can not "make" a given liquid like that but there are some liquids with low surface tension. From the back of my head I remember the Avogadro experiment, but to lazy to look it up. What I recall is that he "counted" the amount of particles in a drop of oil because it forms a mini layer of lying on top of water. You might notice when you drop a bit of oil in water, that it always creates a giant puddle.
Back to the original post: that thin layer of water would just evaporated instantly
wouldn't it also be impossible to drink? The water would just seep out of any cup and find the path of least resistance to the floor
At least with oil you can just raw dog the nozzle and squeeze it directly in, guzzling down those calories by the gallon at least until the attendant starts to run over, but by then you pull out your lighter threateningly and shake your head until he backs off again
This is how science fiction is made!
Special Meta materials are very under-explored, It seems reasonable that in a future high tech society they would be increasingly common.
Mostly we get “faster engines” and “advanced computermachines that sometimes perform unexplained magic”
I'm not a geologist, but I'm imagine that the deep ocean would be a colossal underwater glacier, with intermixed sedimentary layers. Kind of like what we have with methane hydrate deposits, only much, much deeper. The super-deep ocean simply wouldn't exist, and we might not even know about the Mariana Trench, or a lot of other sea floor features. Also, it's possible a different proportion of the world's water would be frozen in this way.
With ice as a part of the sea floor, it would also interact with subduction zones at continental edges. That might push a LOT more superheated water into volcanoes, faults, and everywhere else water could go. That would probably make for a lot more geysers in such areas, and volcanic eruptions would be far more energetic.
The trajectory of human history and technology would also be changed. There might have been fewer ice bridges between continents during the last ice age. Ice-skating wouldn't become as common a thing until we get refrigeration. Harvesting ice in the winter would require bodies of water to freeze solid first, making it impractical except in shallow areas.
I'm also going to wager that glaciers would behave differently too. I don't know enough about their dynamics, but I wonder if having meltwater on the bottom helps lubricate their movements somewhat. Kind of like a lava flow, only slower. Inverting that relationship might make glaciers far less mobile.
Hmm, might small bodies of water, say pusdle to pond size, still freeze from the top down because of exposure to colder air and above freezing earth? If the top freezes over all at once it might stay on top unless something breaks it and allows water to flow from under to over
Season 8 is really good so far. They're taking the stories in a new direction that I really like. I think Justin Roiland leaving might have actually been a positive for the writing.

wouldn't this evaporate extremely quick though?
Yeah, I'll often spread spilled water across the table just so that it evaporates within a couple minutes.
Must be nice living somewhere dry. I’d just end up with a moldy table a day later.

supercritical helium does some really weird shit, I'd call this one plausible.

Superfluid. It can be supercritical, but superfluid is the special thing for helium.
You do some pretty weird shit.
Oh, snaaaaaap.
I'm no geologist, but I could have guessed that without any further specifics 😉
Unless its a hydrocarbon product, which can (and does) spread over surfaces it can't mix with/soak into in single molecules thick sheets.
Aha! But languical constructs allow and do allow hyperboles! So it could be argued that the colleague asked for the minimum allowed by our bindings law!
I request a motion to dismiss your dismissal :>

Yeah, this would be very bad, lol.
If we want to go to extremes, zero surface tension means no nucleation barrier for critical bubbles. In practice, this implies that liquid water is unstable, and will spontaneously vaporise at all conditions.
So yeah, all life ends pretty quickly.
Wow, that's much worse lol!
I think that's part of our anthropic bias, not sure we'd be alive without water's surface tension in order to observe this.
Well cells wouldn’t be circle shaped, but would it actually be to the detriment of life in that or other ways?
Maybe cells could take a more pragmatic shape, like tactical dicks
I think that could make some life-supporting chemical reactions difficult to happen, but I'm not qualified to judge that.
Surface tension and reactions are manifestations of the same underlying phenomenon. I’m certain that causing a change in one would also affect the other.
I don’t, not that I am qualified to say so either! The larger surface area might be beneficial for osmosis!
I'm also not qualified, but I do wonder whether releasing all that surface tension inside us would alleviate a lot of anxiety. I think yes.
I'm qualified, our brains would immediately stop functioning and that does tend to relieve anxiety.
Trees wouldn’t exist, so life would definitely look different.
What are you on about?
Capillary action doesn’t happen without surface tension, so long stemmed woody plants are out. Iirc, mushrooms were not super common before trees and spread by decomposing them, so those are gone too
That's how gasoline spills (on water) work. They cover the water about one molecule thick.
So you’re saying my floor needs to be water?
It'd evaporate much quicker TBF. Although that also means that the BP would be much lower and tea and coffee wouldn't be a thing and boiling wouldn't be a reliable method of cooking. although on the flip side, you could increase the strength of alcoholic beverages by boiling the water off instead of distilling the alcohol.

It would instead instantly make it extremely obvious how uneven my floor is.
At 2 micrometers, it’s going to evaporate too fast for there to be a
puddlethin film of water.Oh! The humidity!
This reminds me of the person that suggested in a response to a request for ADHD “life-hacks” where they would wet one of their socks before starting a specific high-importance task and could not take it off until the specified task was completed.
I see, quite similar to the ol’ light-your-hair-on-fire-to-motivate-yourself-to-shower trick. Clever!
That is a weapons-grade life hack right there.
Goddamn. That's some diabolical hack. I might give it a try.
Well if water didn't have its unique properties of cohesion and adhesion we likely wouldn't be here anyways.
The water would react similarly to alcohol. Yes, the puddle would be bigger but it would evaporate faster.
look....I'm just glad roaches don't have sharp teeth and spiders can't fly.
let's stop while we're ahead
When some spiders are born, sometimes hundreds at a time, they cast little parachute webs and ride the wind to wherever they might go.
Palmetto bugs are like mean flying roaches that bite.
You’ll never escape the horrors of the beauty in nature.
Let's stop
while we're ahead“Palmetto bugs” are just roaches, period. That name refers to either the Florida woods cockroach or the American cockroach.
We would not have life! Water is a polar molecule that is very different from most other liquids. Its the specific surface tension properties that help to create life. The reason why we search for planets with water. We've never worked out a way for any life to exists without the amazing H2O.
Now imagine what wonders we could have if there were a few other quicky molecules.
Every molecule is quirky in its own way..
That's what my mum says!
What if it just applied to chlorinated tap water then
As an odd thought experiment or are we hoping that the laws of physics might be different there? All water, except brand new in reaction space is almost certainly going to contain dissolved ions
Well I think the idea is more that for some reason water needs to be treated with something that removes surface tension if you want to safely pipe it to people's houses. At least that shouldn't destroy all life.
That would actually be a very useful tool for machinists. I think it would make it much easier to find out how non-flat something is
You can add a wetting agent to water to decrease the surface tension
wetter water
I know a guy who drank some WaterWetter and got pretty sick. He was an idiot.
Add more water
Can we make liquids like that? Sounds useful in some situations.
Yes and no. No surface tension implies vanishing intermolecular forces, so the liquid would not be cohesive and would expand in all directions to the volume of the room... which is pretty much the definition of a gas. Not quite though: supercritical fluids also do this as long as temperature and pressure remain high enough, and are indeed useful in niche applications industrially.

Let's see AI try to recreate this coherent incoherence! HUMANS REPRESENT!
wat
we're talking extreme fluid dynamics are we not
So it would actually be more practical, don't need to mop it up if it evaporates.
This is how science fiction is made!
Special Meta materials are very under-explored, It seems reasonable that in a future high tech society they would be increasingly common.
Mostly we get “faster engines” and “advanced computermachines that sometimes perform unexplained magic”
I read that in Meatwad’s voice.
made me reread it
Now think about what would happen if ice didn't float.

Yeah, not good. It's kind of a weird quirk of nature that water is pretty unique in that it gets less dense when it's a solid as well.
The movie Titanic would be boring
Bold of you to assume my floor is level.
Not only that, but level with 2 micrometers tolerance is something only specialized CNC milling workbenches achieve
Yeah, that guy must have a really flat floor
Did someone say oxygen not included?
We're 60% water and not really water-tight as it is.
I love this comment section
Only Rick Sanchez can make a floor that level, and then only 1 square meter.
Season 8 is really good so far. They're taking the stories in a new direction that I really like. I think Justin Roiland leaving might have actually been a positive for the writing.
Would that mean that if you jumped into the Atlantic you'd just fall to the bottom? Or would that be due to buoyancy or something
Buoyancy (different densities).
I'm really dense though
See you at the bottom
we also wouldn't have icicles :(
I hate when I spill some oil or soapy water and it does this
if we lived in a high pressure environment, this totally would happen.
Would it still be possible to have a shower?
Yes.
But you probably wouldn't be alive.
Ever spilled a drop of diesel? Exactly that happens
Then your cells would die and plants wouldn't exist
That response goes so hard. Why is it that shitposts bring our the hardest lines?
