Apparatus used to demonstrate Pascal’s principle of the Equality of Pressure in Liquids.
All metal construction that provides rigidity, sturdiness and durability to the apparatus.

Comprises a removable spherical metal bulb mounted at one end of the cylindrical barrel with piston plunger at the other end. The spherical bulb has a number of holes on its surface with small brass nozzles projecting out. All metal parts either well painted or plated. When filled with water, pushing in the plunger makes water to eject from all the nozzles with equal force.
