Thermometer - Galileo 40cm (Set of 2)

Named after Galileo for his discovery of the principle on which this thermometer is based, the Galileo thermometer was created in the 17th century by the Accademia del Cimento in Florence, which included Galileo’s pupil Torricelli and his student Viviani. The design was documented in 1666, describing it as a “slow thermometer” due to its gradual response to temperature changes. The outer vessel contained 'rectified spirits of wine', and the glass bubble weights were adjusted by grinding the sealed ends. A small air gap at the top allowed for expansion.

The Galileo Thermometer is still used today due to its exceptional and interesting design. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes. The bulbs that rise indicate the current temperature.
