 Galileo Galilei was an important Italian scientist who founded modern physics with its reliance on experience and experiment. Among countless discoveries of natural laws, he succeeded in developing a thermometer based on the law of physics, which states that the specific gravity of liquids changes as they expand at different temperatures. As the temperature rises, the liquid expands, its specific gravity decreases and the spheres sink. The current temperature is indicated by the lowest of spheres, which are still floating. This fun and attractive thermometer makes a great gift. Available in three sizes.
