 (1).jpg)
Product Code : SCL-PLE-10459
The Cartesian Diver (Buoyancy Aid) 3 pcs from Lab Glassware Manufacturer, headquartered in Ambala, Haryana, India, is a physics laboratory kit used for demonstrating pressure, buoyancy, density change and floating-sinking behavior in water. Since 1982, the company has manufactured and exported physics lab equipment, laboratory glassware and scientific instruments to schools, colleges and research institutions worldwide, including growing demand from Melanesia — Fiji, the Solomon Islands and Vanuatu — where school science departments continue to source hands-on buoyancy and pressure demonstration kits.
Quick Answer: The Cartesian Diver is a classic physics demonstration in which squeezing a sealed, water-filled container changes internal pressure and compresses an air pocket inside a small diver figure, changing its density and making it sink or rise, illustrating buoyancy and pressure-density relationships in an intuitive, hands-on way.

A Simple, Memorable Introduction to Buoyancy
Named after René Descartes, the Cartesian diver is one of the most accessible ways to introduce younger students to buoyancy and pressure before moving on to more quantitative apparatus. Because the effect is immediate and visual, it works well as a classroom demonstration or a small hands-on kit for group activities. Lab Glassware Manufacturer also supplies the Buoyancy Apparatus, a more quantitative complement once students are ready for measurement-based experiments on the same topic.
