Cartesian Diver Experiment - Classic Physics Demonstration #1546121 (License: Personal Use)

This illustration depicts a classic Cartesian diver experiment, where a small sealed object (often a pipette or figurine) floats inside a water-filled bottle. When pressure is applied to the bottle cap, the diver sinks due to increased water pressure compressing air inside it; releasing pressure makes it rise again. The image highlights core concepts of Archimedes’ principle and Boyle’s law in an accessible, visual format.

Used in educational websites, science blogs, and classroom resources to explain fluid dynamics and pressure. Matches user intent for DIY science experiments, STEM teaching aids, or physics concept visualization.
