I'm wondering how I could mix two substances, either water or oil and some other stringy/cloudy like substance to permanently create a cloudy, smoky texture that doesn't diffuse. See around 45 seconds in this video https://www.youtube.com/watch?v=VDOWS_JBCfw where he puts the ink into water is what I mean. Obviously over time this will diffuse and lose this smoky shape, what two substances would stay in this way permanently? I was thinking some high viscosity oil like glycerol and another substance, but putting ink into oil just creates little balls, need something that will created long streaks. maybe its not possible.

    there's a lot of characteristics a substance needs to be able to do this. It needs to be hydrophillic so that it spreads out through the water, but not soluble so that it disappears. It needs to have a long molecular structure, or else it will from a homogenous colloid. Two good examples of existing substance that can do what you're talking about are curdled milk and mucus. Those are made of proteins which form long strings which are able to hang in the water.

    Maybe put the ink in epoxy instead of water, and then let it dry. Epoxy might be too thick to let the ink diffuse like that though, so maybe there could be some other step involved. See here where a guy tries to catch a shattered Prince Rupert's drop in epoxy, that's kind of similar but more difficult. If the epoxy is still very fluid right after mixing and hasn't hardened at all maybe you can just add your ink to it and wait. The epoxy will harden and the more it hardens the less the ink will continue to diffuse, so you should have more time than you would with other liquids.
    That said you will end up with a solid object at the end, if you were hoping to get a liquid then I guess that's not the solution.

      This is on the right track, you can thin clear epoxy with alcohol or acetone to loosen it up and set some aside and it dye with alcohol and even water based inks to make the visible part.
      You can also get slow hardeners that give more time for things to disperse, including any bubbles you get from mixing.
      To make a cloud illusion like in the OPs image it's less of a water- like dispersion and more of a wind/convection current thing moving visible vapor around so mechanically moving the colored material by stirring or inducing currents in the container by moving and shaking it will probably work best and give some degree of control.
      Pic related in polyester resin but epoxy is more forgiving and mixes better with a wider range of materials.

      This is more for through-coloring epoxy but has some good tips-

    Thanks for the replies guys. Honestly my aim is to try to create a simulation of earth clouds on a small scale. I was thinking maybe white mica powder in oil. But you are right I will need something with connected molecules to stop diffusion. I think maybe this is impossible to simulate permanently

      It might help if people knew what it was for. There's plenty of ways to make cloud looking shapes that are relatively solid. I don't know if this would work at all for what you want, and it'd likely take some experimentation with resin or whatever to make sure it doesn't dissolve further. https://www.youtube.com/watch?v=Q7qVH0ykCTU

      You've got two great and easily available options right here

      Take the curdled milk and mucus pill.
