Exercise children’s hands-on ability, understand PASCAL’s law and principle, and understand hydraulic transmission.According to PASCAL’s law, a pressure applied to one piston in a hydraulic system must produce the same increase in pressure on the other.  If the area of the second piston is 10 times the area of the first piston, the force acting on the second piston will increase to 10 times the area of the first piston, and the pressure on both pistons will be equal.
