Galileo Thermometer - 10.5"
Galileo Thermometer - 10.5"
Our Price: $19.95

Galileo Thermometer - 10.5" Originally conceived by the Big 'G' himself, Galileo thermometers are both attractive and functional. When the temperature changes, the liquid in the tube increases or decreases in density. The balls with colored liquid have differing weights and thus rise or fall depending on the temperature. To read the temperature, look at the lowest floating ball. If a ball is floating in the middle of the tube, the temperature is between it and the lowest floating bulb.

Galileo Thermometers work from temperatures from 64F to 94F.

Size of thermometer is 10.5” tall. Works with 6 multi-colored float balls.

Fitzroy Storm Glass 11"
Fitzroy Storm Glass 11"

This storm glass is the same size and shape as an 11" Galileo Thermometer.

11"/28cm Tall

The storm glass was popularized by Admiral Robert Fitzroy after his historic voyage on the HMS Beagle.

How the Storm Glass works is still a mystery, and in fact it likely does not predict the weather. But it does react to weather changes, mostly from temperature and makes gorgeous crystal patterns with those changes.
This is a gorgeous decorative gift idea for the adult who has everything or someone who finds meteorology fascinating.

How to "read":
A: Clear Liquid
Bright and clear weather
B: Cloudy Liquid
Sometimes with small stars and crystals at the top. Cloudy weather and often predicts thunderstorms and rain.
C: Small Stars in Liquid

D: Large Flaky Crystals
Cloudy skies, snow in winter.
E: Threads of Crystals At The Top
Winy Weather
F: Crystals At The Bottom,
Frost may be coming.
