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

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

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

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

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

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

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

Oh! The humidity!

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.

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.

wetter water

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.

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.

Liquid with low to none surface tension? Relatively possivle, tensioactives and additives within soaps and washing up liquids can do that.

And lakes affected by this are biologically damaged or dead, as surface tension is essntial to life.

Edit: that line is something they would absolutely add to an ATHF episode, but the consequences would be absurd as usual.
