premise: To prevent the glass bending under gravity, its weight is carried by many distributed reaction forces, which should change with orientation to mimic the buoyant force felt if the mirror were floated in liquid of its own density.
hypothesis: If the buoyant force is greater than the force of gravity acting on a ship, it will float.
