   Anyone ever notice how air bubbles in, or droplets of, low surface tension fluids act very oddly. Speficially i notice they tend to not want to merge and in this case its really weird cause the bubble moves away from the surface as it moves down and the rube narrows. Its likely a sort of cappilary action at play or something.

     @freemo So low surface tension fluid would potentially be subject to the mass of fluid above it and the reduced strength of the Force thing. Less tension holding the sphere together, likely higher pressure at the same depth because of molecular mass and forces being too weak to form a larger bubble with ease.

     So with water and its surface tension I would think that larger bubbles are possible to form at deeper depths. The air sphere would be under more pressure and that pressure would have to overcome the surface tension to have less molecules of air.

     I think an air bubble at sufficient depth would be smaller and grow upon rising. At a certain point it would overcome the forces and make more bubbles. It would be like a histogram. I think the inverse of the histogram would model a low surface tension fluid with all other factors taken into account.

     If these suspicions are partially correct, I wouldn't be surprised. I fully expect to be wrong about something. All I know is that I don't know and I will know that I know less by replying.

     @freemo I think it's a surface tension thing

     @freemo likely surface charge. Ever made ‘anti bubbles’ Great fun. A thin layer of air around a bubble of the liquid. Super stable too.
