The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. So, after the wei...ghted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water.<br><br> As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, thereby changing its density. So, at any given density, some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature.

This beautiful conversation piece combines two ancient technologies - the Admiral Fitzroy Storm Glass and the Galileo Thermometer.... <br><br> <b>The Admiral Fitzroy Storm Glass:</b> <br><br> How this storm glass really works is a mystery, but it is believed that electromagnetic changes in weather patterns activate crystals inside (sealed-glass chamber fills with crystals when air pressure decreases). Famed meteorologist Admiral Fitzroy used a storm glass on a historic voyage (1831-1836) with Charles Darwin <br><br> A storm glass works on the premise that temperature and pressure affect solubility, sometimes resulting in clear liquid; other times causing precipitants to form. However, the method by which this works is not fully understood. Although it is well-established that temperature affects solubility, some studies have simultaneously observed several different storm glasses forming similar crystal patterns at different temperatures. In addition, sealed glasses are not exposed to atmospheric pressure changes and do not react to the pressure variations associated with weather systems. <br><br> <b>The Galileo Thermometer:</b> <br><br> The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture. <br><br> Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of each tag is slightly different from the others. Since the bubbles are all hand-blown glass, they aren't exactly the same size and shape. <br><br> The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. So, after the weighted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water. read more

This handsome unit uses a blend of old and new technology to interpret the weather. The Galileo thermometer is filled with a clea...r liquid that suspends multiple colored weights. As the liquid within the weights changes temperature their density changes allowing the weights to rise or fall. The lowest weight at the very top of the Galileo reflects the temperature. The glass water barometer indicates changes in the air temperature. A low fluid level in the glass spout generally means fair weather while a higher fluid level in the glass spout means foul weather approaches. read more

The 13-inch glass Galileo thermometer combines style and functionality as a beautiful accent piece for any home or office. Not onl...y does it measure indoor temperature, it is a work of beauty and art. Makes a great gift item and lasting conversation piece! Galileo Galilei, the pioneer of modern astronomy and physics, (1564-1642), discovered that liquids change density as the temperature increases or decreases. Based on this principle, the colored glass spheres inside the glass Galileo thermometer have been precisely weighted so that they respond to temperature changes. When the temperature rises, the liquid inside the Galileo thermometer becomes less dense and the colored spheres floating inside will sink towards the bottom. When the temperature of the room cools, the process is reversed and the spheres will rise from the bottom. One-year limited warranty. It's more than accurate, it's AcuRite. read more
