Cartesian Diver

The video explains the principles of buoyancy and weight using a Cartesian diver model. It demonstrates how changing pressure in a sealed bottle affects the diver's buoyancy, causing it to rise, sink, or hover. The experiment uses a plastic straw, sticky tack, and water to create the diver. The video also compares this concept to how submarines use ballast tanks to control buoyancy.
