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. A science apparatus manufacturer in India, Science Lab Supplies makes the demonstrator on its factory floor at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and quotes it to schools, colleges, tender contractors and distributors itself.
Specifications
Sphere, openings and piston of Pascal's ball are each described in their own row below. In short, a metal sphere of 8 cm diameter with multiple small openings or nozzles is attached to a tube holding a tightly fitted piston, so that when the piston is pushed the liquid leaves every opening and shows equal transmission of pressure.

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 suits the fluids chapter of Class 11 physics, the pressure topic of middle-school science, and introductory fluid mechanics in polytechnic courses, where pressure transmission comes before hydraulic calculations.
- Class 8 science: liquids exert pressure in all directions.
- Class 11 physics: Pascal's law and its use in hydraulic machines, then measuring liquid pressure on a U-Tube Manometer on Stand Table Model.
- Diploma fluid mechanics: introducing pressure transmission before hydraulic press calculations, and comparing it with the double-valve Force Pump.
Water can be used for the demonstration; 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. A catch tray or other fluids apparatus for the same lesson can be added to the quotation as separate lines.
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.
With its Importer-Exporter Code, Science Lab Supplies is a registered exporter able to ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. For a fluids-bench price, describe your requirement on the contact page or put the demonstrator in the enquiry cart; bids from institutions go through the lab tender page.
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, connected to the tube in which the tightly fitted piston moves.
Is Science Lab Supplies the manufacturer or a trader?
Pascal's demonstrators are made in the firm's own Saha, Ambala factory in India; Science Lab Supplies is therefore the manufacturer, and the price and delivery schedule on each quotation come straight from it.
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, alongside any other fluids apparatus in the tender.
