wouldn't this evaporate extremely quick though?

[–] Signtist@bookwyr.me 64 points 11 hours ago (1 children)

Yeah, I'll often spread spilled water across the table just so that it evaporates within a couple minutes.

[–] anomnom@sh.itjust.works 2 points 2 hours ago

Must be nice living somewhere dry. I’d just end up with a moldy table a day later.

[–] LostXOR@fedia.io 112 points 10 hours ago (3 children)

For a liquid to be a liquid, rather than a gas, it needs to be held together by intermolecular forces. Which means it will have some amount of surface tension. I therefore dismiss this hypothetical as physically unrealistic! :P

[–] _stranger_@lemmy.world 48 points 10 hours ago (4 children)

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

[–] LostXOR@fedia.io 23 points 10 hours ago (1 children)

Supercritical fluids are more like a gas than a liquid. Their lack of surface tension means they'll diffuse throughout whatever container you put them in, so they can't really be "poured" like a liquid can. They're actually a pretty good example of why liquids need surface tension to be liquid.

[–] _stranger_@lemmy.world 17 points 10 hours ago (1 children)

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.

[–] thebestaquaman@lemmy.world 2 points 6 hours ago

"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).

[–] zout@fedia.io 7 points 8 hours ago

Superfluid. It can be supercritical, but superfluid is the special thing for helium.

[–] SatansMaggotyCumFart@piefed.world 5 points 9 hours ago (1 children)

You do some pretty weird shit.

[–] ivanafterall@lemmy.world 2 points 6 hours ago

Oh, snaaaaaap.

[–] Viking_Hippie@lemmy.dbzer0.com 1 points 5 hours ago

supercritical

I'm no geologist, but I could have guessed that without any further specifics 😉

[–] Derpenheim@lemmy.zip 9 points 7 hours ago

Unless its a hydrocarbon product, which can (and does) spread over surfaces it can't mix with/soak into in single molecules thick sheets.

[–] theUwUhugger@lemmy.world 4 points 10 hours ago

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 :>

[–] lemmy_outta_here@lemmy.world 34 points 7 hours ago (1 children)

at least it wouldn’t wet your socks. i think capillary action relies on surface tension

[–] thebestaquaman@lemmy.world 24 points 6 hours ago (1 children)

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- energy, so you get a capillary effect.

If water had exactly zero surface tension against every interface,

  • it would not exhibit any capillary action
  • life on earth would cease to exist quite quickly
  • your socks would remain dry

[–] eager_eagle@lemmy.world 27 points 11 hours ago* (last edited 11 hours ago) (1 children)

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.

[–] theUwUhugger@lemmy.world 4 points 10 hours ago (2 children)

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

[–] eager_eagle@lemmy.world 3 points 9 hours ago (1 children)

I think that could make some life-supporting chemical reactions difficult to happen, but I'm not qualified to judge that.

[–] theUwUhugger@lemmy.world 1 points 8 hours ago (1 children)

I don’t, not that I am qualified to say so either! The larger surface area might be beneficial for osmosis!

Trees wouldn’t exist, so life would definitely look different.

[–] MyTurtleSwimsUpsideDown@fedia.io 24 points 9 hours ago (2 children)

Bold of you to assume my floor is level.

[–] Eggymatrix@sh.itjust.works 7 points 8 hours ago

Not only that, but level with 2 micrometers tolerance is something only specialized CNC milling workbenches achieve

[–] Hjalamanger@feddit.nu 2 points 6 hours ago

Yeah, that guy must have a really flat floor

[–] yucandu@lemmy.world 24 points 8 hours ago* (last edited 8 hours ago) (1 children)

That's how gasoline spills (on water) work. They cover the water about one molecule thick.

[–] RememberTheApollo_@lemmy.world 4 points 7 hours ago

So you’re saying my floor needs to be water?

[–] don@lemmy.ca 21 points 10 hours ago* (last edited 10 hours ago) (1 children)

At 2 micrometers, it’s going to evaporate too fast for there to be a ~~puddle~~ thin film of water.

[–] MyTurtleSwimsUpsideDown@fedia.io 14 points 9 hours ago

Oh! The humidity!

[–] JaymesRS@piefed.world 13 points 6 hours ago (2 children)

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.

[–] EldenLord@lemmy.world 6 points 4 hours ago

I see, quite similar to the ol’ light-your-hair-on-fire-to-motivate-yourself-to-shower trick. Clever!

[–] Ruthalas@infosec.pub 5 points 4 hours ago

That is a weapons-grade life hack right there.

[–] BedInspector@lemmy.world 12 points 4 hours ago

Well if water didn't have its unique properties of cohesion and adhesion we likely wouldn't be here anyways.

[–] aeronmelon@lemmy.world 10 points 11 hours ago (2 children)

I read that in Meatwad’s voice.

[–] ramenshaman@lemmy.world 10 points 7 hours ago* (last edited 1 hour ago)

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

[–] uriel238@lemmy.blahaj.zone 8 points 1 hour ago

The water would react similarly to alcohol. Yes, the puddle would be bigger but it would evaporate faster.

[–] Lupus@feddit.org 8 points 11 hours ago

Did someone say oxygen not included?

[–] DarrinBrunner@lemmy.world 7 points 11 hours ago (1 children)

Only Rick Sanchez can make a floor that level, and then only 1 square meter.

[–] Feathercrown@lemmy.world 3 points 9 hours ago

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.

[–] Almacca@aussie.zone 7 points 4 hours ago (1 children)

Now think about what would happen if ice didn't float.

[–] dejected_warp_core@lemmy.world 10 points 3 hours ago* (last edited 3 hours ago) (1 children)

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.

[–] pixeltree@lemmy.blahaj.zone 2 points 55 minutes ago

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

[–] jaileh@jlai.lu 6 points 8 hours ago

I love this comment section

[–] Droggelbecher@lemmy.world 5 points 10 hours ago

I hate when I spill some oil or soapy water and it does this

[–] betahack@lemmy.world 3 points 1 hour ago

look....I'm just glad roaches don't have sharp teeth and spiders can't fly.

let's stop while we're ahead

[–] bobo1900@startrek.website 3 points 8 hours ago

Ever spilled a drop of diesel? Exactly that happens

[–] Battle_Masker@lemmy.blahaj.zone 3 points 9 hours ago

That response goes so hard. Why is it that shitposts bring our the hardest lines?

[–] DragonTypeWyvern@midwest.social 1 points 1 minute ago

Then your cells would die and plants wouldn't exist
