20cm Galileo Thermometer Pocket Watches Made in Scotland by PewtermillThese distinctive ornamental (but functional) thermometers utilise 17th century astronomer Galileo Galilei's discovery that the density of liquids varies with temperature. Carefully weighted glass globes are suspended in a liquid filled tube, where they sedately sink or float as the surrounding air gets hotter or colder. Temperature is indicated by the engraved brass tag on the lowest floating globe. Measures 8" tall.
