Fountain Experiment Diagram - Physics Principle Demonstration #9089 (License: Personal Use)

This black-and-white line drawing depicts a classic physics demonstration known as the “fountain experiment,” where water in a lower reservoir is drawn up through a narrow tube into a bulb, then expelled upward as a jet due to air pressure differences. The setup includes a sealed bulb partially filled with water, connected via a tube to a water source below, with a stopcock or constriction controlling flow. The diagram highlights fluid dynamics principles such as atmospheric pressure, capillary action, and Bernoulli’s effect in a simplified educational format.

Used in physics textbooks, classroom presentations, and online STEM learning modules to explain pressure-driven fluid motion; targets students and educators seeking visual aids for foundational mechanics concepts.
