Crushing Can
Product Code : LSK-PL-10302
Crushing Can (SKU LSK-PL-10302) is a light-walled tin plate can with an air-tight screw cap for demonstrating the force exerted by atmospheric pressure. When the air inside is driven out and the pressure inside drops, the outside air crushes the can in front of the class. It suits pressure lessons from middle school to Class 11. The can is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quoted directly to schools, colleges and distributors.
Specifications
Material, closure and size of the can take one row each. In short, it is made of light-walled tin plate so it gives way under atmospheric pressure once the pressure inside is reduced, an air-tight screw cap seals it at the right moment, and it measures 260 mm long by 75 mm in diameter.

Applications and Experiments for the Crushing Can
The demonstration makes an invisible force obvious. A little water is boiled in the open can so steam drives out the air; the cap is then screwed on and the can cooled. As the steam condenses, pressure inside falls and atmospheric pressure crushes the thin walls within moments.
- NCERT Class 8 science: force and pressure, including atmospheric pressure.
- Class 9 science: pressure in fluids and the effects of air pressure, with the water heated on an Electric Hot Plate.
- Class 11 physics: mechanical properties of fluids and pressure differences.
- Following up with the pull-apart test of the Magdeburg Hemispheres.
Never heat the can with the cap screwed on. Steam and the hot can can scald, so the teacher should handle it with heat-resistant gloves or tongs and keep students at a safe distance.
Standard Scope of Supply
The Crushing Can is supplied as a single tin plate can with its air-tight screw cap. A heat source and tongs for the demonstration can be added to the quotation, and because the can is crushed in use, several cans may be needed for repeated demonstrations.
Packing, MOQ and Lead Time
Order a few cans for one demonstration or enough for every class in the year; each quotation sets out the packing, delivery time and price for that number. Vacuum pumps, bell jars and other air pressure apparatus can be quoted with the cans.
As a registered exporter holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. Tell us how many cans the year’s classes will need via the contact page, keep the count in the enquiry cart, or tender for them on the lab tender page.
Frequently Asked Questions
How does the Crushing Can demonstration work?
Steam from boiling water pushes most of the air out of the open can. After the cap is closed and the can cools, the steam condenses, the pressure inside drops, and atmospheric pressure crushes the can.
Can a can be reused?
A crushed can cannot normally be restored, so plan one can per demonstration and order enough for all the classes you teach during the school year.
Is Science Lab Supplies the manufacturer or a trader?
Tin plate cans for this demonstration come from the Science Lab Supplies factory in Saha, Ambala, India, where they are manufactured; quotations are therefore issued directly by the maker.
What size is the can?
It is 260 mm long and 75 mm in diameter, made from light-walled tin plate with an air-tight screw cap that seals the can once the air has been driven out.
