Detailed product description

Overall height: 11.4 inches tall Barometer height: 5.9 inches Number of glass balls: 5 Glass Galileo thermometer range: 64ºF to 80ºF Temperature is determined by lowest floating bulb Glass barometer globe with frosted world map Low level of liquid in spout = high pressure and fair weather High level of liquid in the spout = bad weather Attractive wood base and wood framed hygrometer Ambient Weather 1 year warranty Add food coloring to customize the water barometer color (not included). Distilled water is recommended but not required (not included, water must be added to the barometer).

The Galileo thermometer consists of a sealed glass tube that is filled with liquid (paraffin oil) and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture. 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. 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 liquid. As the temperature of the air outside the thermometer changes, so does the temperature of the liquid surrounding the bubbles. As the temperature of the liquid 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. A narrow spout connects to the body below the liquid level and rises above the water level, where it is open to the atmosphere. When the air pressure is lower than it was at the time the body was sealed, the water level in the spout will rise above the water level in the body and when the air pressure is higher, the water level in the spout will drop below the water level in the body.
