The Galileo Thermometer

The video introduces the Galileo thermometer, named after Galileo Galilei, explaining its principle based on the density change of liquids with temperature. The thermometer consists of a glass cylinder with a clear liquid and color-coded balls of varying densities, each representing different temperatures. The video demonstrates how the thermometer indicates the current room temperature and includes an experiment to show its functionality.
