Quick Answer: The Simple Pascal Law Experiment (Pressure String) is a fluid pressure apparatus with a 50 mm spherical chamber pierced by orifices all round and an internal piston. Pushing the piston makes liquid spurt out of every hole at once, showing that pressure acts equally in all directions.

About This Product
Filled with water and squeezed by the piston, the sphere sends out jets of similar strength from holes facing every direction. It gives a clear first demonstration of Pascal’s law: pressure applied to a confined liquid is passed on equally throughout it, the idea behind hydraulic presses and brakes.
Frequently Asked Questions
What does the Simple Pascal Law Experiment (Pressure String) show?
When the piston is pushed, liquid leaves all the orifices around the 50 mm sphere at once, showing that pressure in a confined liquid acts equally in all directions.
