It's interesting to me that a liquid, under the force of gravity, in a container has a flat surface. Tell me if my explanation is correct: if the surface of the liquid were uneven, the higher parts of it would be "sitting on top of" the liquid below. Necessarily, the liquid under these parts would have higher pressure than the rest. Pascal's principle says that this cannot be the case, so the pressure equalizes throughout, allowing the higher liquid to fall and raising the lower liquid, flattening out the surface.
