It is a Law applied in the field of physics and chemistry that shows how a homogeneous liquid can have the same level when poured into a series of containers connected through conduits without the shape or orientation of the glasses affecting the level.. This liquid, which is in a state of rest when added with more liquid of the same consistency, will increase its volume but will maintain the level in all glasses. The level of the liquid in the glasses will be maintained even when they are tilted.
The scientific principle on which this theory is based points out that it is atmospheric pressure and gravity, two constant values that act directly on the liquid contained in the glass, pushing downwards in a uniform way regardless of the geometry of the container. This principle was introduced by Blaire Pascal who asserted with his studies that "The pressure that is exerted on a mole of liquid is transmitted in its entirety and with the same intensity in all directions". This was called "Pascal's Principle".
The application, as we said before, is in the field of physics and chemistry, it is ideal for measuring the correct homogeneity of a liquid as well as for establishing the correct atmospheric pressure data. In ancient times this principle was used to distribute water through the different communities that used a vein of water emanated from a river or mountain, semi-deep water wells were dug connected through a pipeline and these were filled with enough water to supply a home, but at the same time the course of the current allowed the water to also reach an adjoining well that will work equally for another house.
Arqueólogos de todo el mundo al concluido que las diferentes civilizaciones a través del tiempo demostraron su capacidad de construir grandes ciudades y sistemas de servicios básicos con estructuras como los vasos comunicantes. En Roma y la Antigua Grecia se diseñaron no solo sistemas para agua de uso doméstico sino para también mantener el riego de los ornamentos de la ciudad que se basaban en diseños barrocos y coloniales.
