Communicating vessels 2 / 3

As hydrostatic pressure varies with depth, any point, like A, B and C which are in the same mass of liquid and at the same depth, should have the same pressure. 

A paradox: It would seem to be "common sense" to think that the receptacle which containes more water, and the walls of which converge towards the base, would experience greater pressure, but that is not true: Physics demonstrates this and the experiment confirms it.
