One can, at this point mention the problem of the water tanks. Two
identical cylindrical water tanks are connected at the bottom by a pipe
with a valve which is closed. One is filled with water to height h, the
other is empty. The valve is opened and water flows. Finally the tanks
reach equilibrium with each being filled to height h/2.

To prevaricate in the best dilettante manner, I should note that two
tanks connected in this manner make a rather sensitive micromanometer.

It is necessary to introduce an air bubble at the center of the slender
transparent pipe connecting the sealed tanks.

Then the bubble's movement is a very sensitive reflection of the pressure
difference in the air space above the two containers.
