Made from hand-blown glass — The earliest barometers were simple glass bulbs with a spout that helped ancient seaman predict storms. Water moving up the spout means low pressure with potentially stormy conditions, while high pressure pushes the water down to the bottom of the spout. This style of barometer is just as effective today, and provides a decorative method for predicting weather via changes in air pressure. — When good weather approaches, the liquid in the ball is pushe (more…)

This handsome unit uses a blend of old and new technology to interpret the weather. The Galileo thermometer is filled with a clear 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 (more…)
