Product Code : SCL-SK-12143
Anti Gravity Cone (Double Cone Appears) (SKU SCL-SK-12143), often called the double cone paradox, is a mechanics demonstration in which a double cone seems to roll uphill on diverging inclined rails. Physics teachers use it to teach centre of gravity, stability and potential energy in schools, colleges and exhibitions. Science Lab Supplies manufactures the apparatus in-house at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India; schools, colleges, tender contractors and distributors buy it directly from there.
Specifications
The apparatus consists of a double cone and a V-shaped pair of rails that rise and spread apart. As the cone moves toward the wide, high end, its axle sinks between the rails, so its centre of gravity actually falls. Cone and rail material, dimensions, rail angle and finish are confirmed on the quotation.

Applications and Experiments for the Anti Gravity Double Cone
The teacher places the cone at the narrow, low end of the track and lets go; it rolls toward the raised end, and students work out that its centre of gravity is descending. It suits centre-of-gravity and energy lessons in secondary physics, college mechanics and science exhibitions.
- Class 11 physics: centre of mass and centre of gravity of a rigid body.
- Gravitational potential energy: why bodies move so that the centre of gravity falls.
- Stability and rolling motion in applied mechanics.
- Discussing a physical paradox in STEM clubs and exhibitions.
Release the cone gently rather than pushing it, and keep fingers out of its rolling path.
Standard Scope of Supply
The Anti Gravity Cone (Double Cone Appears) is supplied as one demonstration set built around the double cone and its diverging rail track. Base design and any activity guide or storage box depend on the version offered, and the quotation lists the exact parts of the set.
Packing, MOQ and Lead Time
Price one set for the physics demonstration bench, or a quantity for several schools. The quotation shows packing, delivery time and price for that number, and other science kits for students in India, including the Newton's laws apparatus below, can join the same quotation.

Frequently Asked Questions
Does the cone really move against gravity?
No. It only appears to roll uphill. Because the rails spread apart as they rise, the cone's axle drops between them, so its centre of gravity moves downward throughout the motion.
Why is it called an anti-gravity cone?
The name comes from the surprising uphill motion. The physics explanation is ordinary gravity: the cone moves in the direction that lowers its centre of gravity, which makes it a good discussion starter.
Is Science Lab Supplies the manufacturer?
Yes. The company is a science kit manufacturer in India and makes this double cone set at its own factory in Saha, Ambala; quotations are prepared there rather than by a trading agent.
What is the cone made of?
Material is not fixed on this listing. Ask through the contact page and the quotation will state the cone and rail materials of the set offered.
