Galileo thermometer

The Galileo thermometer is both a stylish decoration and a fascinating scientific instrument. Based on principles developed by Galileo Galilei, this thermometer displays the temperature using floating glass spheres in a cylinder filled with liquid. As the temperature changes, the spheres rise or fall, and the bottom floating sphere provides an accurate temperature reading. Perfect as a gift for the science enthusiast or as an eye-catching decoration in the home. Size: 10.8 x 8.3 cm

Did you know?
The Galileo thermometer works because of differences in density - one of Galileo Galilei's many important discoveries in physics. As the liquid heats up, it becomes less dense and the glass beads will sink or float based on their weight relative to the liquid.
