    It’s interesting because very pure water without asperites can be heated above 100c at standard pressure at sea level without boiling. But once impurities are added to it it starts boiling vigorously!

      Sounds like the same thing that happens at 0°C with very pure water that stays liquid, but shake it and bam! It insta-freezes.

        Sometime water bottles display this trait in temps just below freezing. Liquid water in the bottle but break the seal and pop! Frozen

        Doesn’t have to be pure for that! I’ve seen it happen with those cheap plastic sleeve popsicles. It’s kind of fun flicking them and watching the ice radiate through.

        Imperfections in the surface of the container the water is in. Sorry, I intended to write ‘water in a container without asperites’!

          Hm, still not sure what “asperites” are. You seem to be describing asperities.
