Galileo Thermometers are magnificent creations that make Galileo's 400 year old principle of relative density a functional reality. An accurate indoor thermometer encased in brilliant glass, the Galileo is the point at which art meets science and adds sparkle and focus to any setting. Each of the liquid-filled floats weighs grams more than the one above it in the cylinder to ensure a stately and orderly procession of ups and downs as the temperature changes. To accomplish this balancing, the tags on which the temperature is marked are attached by hand. The fluid in the floats and the cylinder has to be exactly the same density for the thermometer to function properly. Four hundred years ago Galileo discovered that specifically weighted floating bubbles would predictable rise or sink in a liquid as the temperature of that liquid is changed. Simply read the tag on the lowest floating bubble to read the temperature.
Fitzroy’s storm glass is a mysterious phenomenon, utilized by meteorologist Admiral Robert Fitzroy as he sailed in the 18th century, most notably as captain of the HMS Beagle during Charles Darwin's famous voyage. A special combination of liquids inside the glass is able to predict weather changes with the appearance of streaks, cloudiness, flakes and crystals.
