Galileo Thermometer is a marriage of science and art.
Amazing! 400+ years ago, Galileo discovered that as a liquid's temperature changes, so will an object's flotation in it... the relative density. That's the science behind this cool Thermometer! Five hand-blown glass spheres (8 in 17" unit), each fitted with a metal medallion, float in a craftsman-blown cylinder. They rise and fall. You read the lowest sphere near the top, determining the room temperature to about 1 degree accuracy. Fascinating laws of physics!
