    The problem with water is it's heavy af. We need a light water.

      Yeah, it's been 15 years since I've taken oceanography, but the density of water is determined by its temperature.

      Density is certainly changeable in water with temperature, but density isn't exactly the same thing as compression.

      TIL A waterjet cutter pressurizes the water to something like 90,000 psi and it gets about 14% more dense. I always thought those things just had the water highly pressurised, but not actually compressed.

          I've noticed that the nerd meme communities here are just as, if not more, pedantic than the ones on reddit

          Edit: oh yea that's also literally the first thing I thought when I read the post, whoops, I'm also a pedantic nerd, I just didn't bother commenting it

            Pure water isn't a good conductor, it needs other stuff mixed in to be a good conductor. Not sure why they deleted their comment. They weren't the one being pedantic, they were complaining that other people in this thread had no sense of humor for calling out the mistake in the original pic.

              I want to posit that because water isn't compressible at forces we experience commonly, it doesn't mean it isn't compressible. For 99.999% of the water rules we concern ourselves with water should be considered incompressible, but there are exceptions to every rule

                But then the conductivity perishes as the salt is being spent. Just add more salt, then?

                            If you think water is incompressible, you’re not trying hard enough.
