G is for Galileo Thermometer
What, for goodness sake, is a Galileo thermometer? Glad you asked. It's a sealed glass cylinder containing a clear liquid, and several glass vessels, or floats, of varying density, which rise or fall as the surrounding temperature changes. Good to know, eh?
This one, on my computer stand, has seven colorful floats, each with a temperature gauge, ranging from 70°, 72°, 74°, 76° 78°, 80° and 82°. At the time I grabbed this shot, the gap between the two floats indicates the temperature was between 72° and 74°F.
** And for those who want to gain a little more knowledge, in order to make that degree symbol, for Windows - you just have to press the ALT key and then 0176 on the numeric keypad. Genius!
