Bring science, history and elegant design together with the Galileo Thermometer 28cm. Inspired by the discoveries of the renowned Italian scientist Galileo Galilei, this fascinating instrument demonstrates the principles of density and buoyancy in a beautiful, easy-to-understand way.

Inside the sealed glass cylinder are six colourful, hand-blown glass spheres, each carefully weighted with a small metal tag. As the surrounding air temperature changes, the density of the clear liquid inside the thermometer changes. The spheres rise or fall accordingly, with the lowest floating sphere indicating the current temperature.

Originally based on principles discovered by Galileo over 400 years ago, the Galileo Thermometer remains a timeless example of science in action. While Galileo did not invent the thermometer itself, his pioneering work on the relationship between density and temperature laid the foundation for this elegant scientific instrument.

Perfect for classrooms, STEM learning spaces, offices or homes, the Galileo Thermometer sparks curiosity while serving as a unique decorative piece.
