Yes, water and other fluids are self-leveling but some of us have built artifical horizons using mirrors or polished metal. The problems then are a- is the mirror flat and b- is the surface level. You have neither problems with liquid but with liquid you have problens with wind ripples or freezing or posion.
The discussion has been on how to set up or improve a mirror AH.
