To demonstrate the underlying physics behind hydraulics in a fun and hands-on approach, a hydraulic claw was constructed out of particle board and plastic syringes. Liquids are incompressible so any pressure exerted on a liquid will be felt by all surfaces in contact with it. By varying the area over which a pressure is exerted, the resulting force can be controlled. The hydraulic claw demonstrates how the incompressibility of liquids can be used advantageously and teaches kids about the fundamentals of hydraulics.
