Pascal’s principle states that the pressure applied to a static fluid is transmitted uniformly to every point of the fluid. To demonstrate this principle, Pascal invented this syringe in 1653. It consists of a piston plunger connected to a sphere with holes, filled with water. When the plunger is depressed, the water squirts out with equal force in all directions. The hydraulic press works on the same principle.
