      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,

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

        life on earth would cease to exist quite quickly

        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…

        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.

    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…

    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

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

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

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

    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.

      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.

    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

      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.
