Sound travels through water (hello Dolphins!) so compression/expansion is possible. I imagine shaking will create those kinds of waves and allow molecules to mi

  Liquids are almost not compressable at all, how that would work? Shaking a container filled 100% water/oil with human strength would make it mix?

    There is no "not ... at all" in physics. Liquids have, strictly speaking, a very very low coefficient of compressibility, but are not absolutely incompressible.

    Key word, "almost." Taking the incompressibility of liquid too literally could mislead one to think that liquid in a sealed tube could be used for faster than light communication. I imagine that much would depend on the shape of the bottle and the kinematics of the shaking. If it's a perfect cylinder, and the shaking is perfectly aligned with the axis of the cylinder, then perhaps no mixing would occur*. But if you shake a plastic soda bottle, the nubbins on the bottom would make areas of lower and higher pressure, which could induce turbulence. Also surface effects would be interesting -- either oil or water could be stickier, which could result in films, then droplets, being separated from one fluid into the other. * though, shockwaves could conceivably form circular vortices...
