Galileo Thermometer

Rising to the Occasion. Despite its scientific shape, it is easy to read this mouthblown glass iteration of the Galileo Thermometer, which displays temperatures in 2°F increments from 68° to 80°. Simply identify the lowest floating sphere and its tag will indicate the temperature with an accuracy within 2°.  15"h. x 3.125"dia.
