Handsomely housed in an antique wood spindle, this Limited Edition Antique Frame Galileo Thermometer—whose colorful spheres of varying density ascend/descend as the temperature changes—indicates the Fahrenheit temperature with an accuracy within 2°, between 68° and 80°. The tag on the lowest floating sphere designates the temperature. Glass. Easy assembly. Indoor use only.
Named for the physicist Galileo—who discovered the principle that liquid density changes in relation to its temperature—the Galileo Thermometer was actually invented by a group of Florentine academics and technicians in 1666. In addition to some of Galileo's own personal correspondence cataloged in our Smithsonian Institution Libraries, our National Air and Space Museum curates an extensive collection of weather-data gathering devices, including a 16mm weather observation camera, a Pibal weather bureau and numerous meteorological satellites.
14"h. x 4"dia.
