Outdoor Galileo Thermometer

Elegant glass tower reveals the current outdoor temperature using a law of physics proven by Galileo: that the density of fluid is linked to its temperature. Each of the 11 glass temperature balls (50 degreesF to 100 degreesF, in 5-degree increments) are precisely weighted with colored fluid, and fitted with a gold-plated Fahrenheit temperature medallion. All you do is look at the lowest-temp. ball that's floating to determine the temperature! Sturdy, 3"-dia. burnished brass framework. Hand-crafted in Germany of mouth-blown glass. 1-1⁄2"-dia. tube; 17-3⁄4" tall overall with hanger.
