Pascal's Law Demonstrator
Product Code : LSK-POM-11197
Pascal's Law Demonstrator (SKU LSK-POM-11197), also known as Pascal's ball, shows that pressure applied to an enclosed fluid is transmitted equally in all directions. Pushing the piston makes liquid spray evenly from nozzles all round a metal sphere. It supports fluid-pressure lessons in school and diploma physics. Science Lab Supplies, a science apparatus manufacturer in India, makes it at its factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, and supplies schools, colleges, tender contractors and distributors directly.
Specifications
The demonstrator consists of a metal sphere of 8 cm diameter with multiple small openings or nozzles, attached to a tube that contains a tightly fitted piston. When the sphere and tube are filled and the piston is pushed, liquid leaves every opening with similar force.

Applications and Experiments for the Pascal's Law Demonstrator
The apparatus gives a direct, visible proof of Pascal's law, the principle behind hydraulic lifts, brakes and presses. It is used for the fluids chapter of Class 11 physics, the pressure topic of middle-school science, and introductory fluid mechanics in polytechnic courses.
- Class 8 science: liquids exert pressure in all directions.
- Class 11 physics: Pascal's law and its use in hydraulic machines.
- Diploma fluid mechanics: introducing pressure transmission before hydraulic press calculations.
Water is normally used; filling with a little colour makes the jets easier to see, and a tray underneath catches the spray.
Standard Scope of Supply
The demonstrator is supplied as a single unit: the 8 cm metal sphere with its nozzles and the attached tube with tightly fitted piston. Water, colouring and a catch tray are not part of the item; any optional accessories are shown separately on the quotation.
Packing, MOQ and Lead Time
A quotation can be raised for one demonstrator or for several across different schools or campuses. It records the packing, delivery time and price for the number requested, and hydraulic press models or other fluids apparatus can go on the same quotation.

Frequently Asked Questions
What does Pascal's ball demonstrate?
It demonstrates Pascal's law: pressure applied to an enclosed fluid is transmitted equally in all directions, so liquid sprays out of every nozzle on the sphere when the piston is pushed.
What size is the sphere?
The sphere is metal with a diameter of 8 cm and has multiple small openings or nozzles around it.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures the demonstrator. It is made at the firm's own factory in Saha, Ambala, India, and the price and delivery schedule on each quotation come from the manufacturer.
Can it be listed in a school tender?
Yes. Send the tender quantity and delivery point, and the item-wise quotation will include the demonstrator with the specification above.
