Well THIS is much more complicated than it looks! You CANNOT have any muck in your glass dish. It’s hard to get the camera level with the water. It’s difficult to focus. If it’s on the floor (because a lot of water is heavy) it’s hard on the back. There are significant variables in sort of oil, quantity of oil, use of washing-up liquid. Lighting it is difficult. Wow. Will keep trying. Probably.
