  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.

  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 alao 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 then you pull out your lighter and shake your head until he backs off

        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 and grossly 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”
