Hydraulic Syringes Multiply Force

Motion/force differs depending on piston sizes. Ask students to predict what will happen. Connect filled syringes and push small vs large piston. Key idea: Pressure transmits through liquid; force depends on piston area. Ask: Which syringe gives more force and which gives more motion? Safety and cleanup: Needle-free; water tray. https://www.google.com/search?q=%22Hydraulic+Syringes+Multiply+Force%22+science+demonstration+experiment
