@mrvanloh I thought brownian motion also affected particles of the same size, which is why they're always moving, sort of bouncing off each other. The repellent force of electrons. I would think as they bounced around, it would create variations in the different densities as well. Electricity always chooses the path of least resistance, in this case the denser groups of water. The ocean is a bad example because it's moving so much. I would think it could be proven with extremely high low amperage and high voltage terminal connected to a slide of water under the proper microscope. If I had them I'd do it. Might prove helpful in superconductor development.
