Does water float?
Since I came up with this question, it has created quite a lot of debate as it's not as simple as it at first appears. If water doesn't float, then what is the water on the surface moving on, surely it floats as one bit of water on the top can be moving in the opposite direction to the water lower down.
However, maybe water is an entity in its own right - something can't float upon itself can it?
