Your discussion made me think on how one could make a mirror float in a way that it is level with fairly high accuracy. I think this is a question of the selected materials. A possible combination could consist in using e.g. glycerin as liquid which has a higher density than water and a plastic to carry the mirror. Polypropylene and Polyethylene have slightly lower densities than water. I'm not really a handy man but I could imagine that such a plastic could be cut or machined to higher dimensional accuracy than e.g. wood. Marcel
