History of the Galileo
The physicist Galilio Galilei (1564-1642) discovered that density of liquid changes according to temperature. This principle is used within the Galileo Thermometer, Depending on the temperature, the glass bulbs in the thermometer either rise or fall. The actual temperature is shown by the lowest of the upper floating glass coloured bulbs.
These Galileo's are top quality and not to be confused with cheaper imitations. Made from blown glass in Germany they really do make a perfect gift that will be admired- certainly not another dust collector.
