Galileo Thermometer/Goethe Ball Barometer for Home Use

These unusual thermometers feature colorful orbs that rise and fall to indicate the current temperature. The model also includes a Goethe weather ball barometer at its base. Crafted from high-quality glass and individually calibrated, this item achieves an accuracy of 2°F while accurately displaying changes in barometric pressure.

To read the current temperature, observe the number written on the hanging tab on the lowest sphere in the top group. To observe changes in barometric pressure, slide the plastic marker to the current water level in the spout. When the water level lowers, the weather will improve, and when the lever rises, poor weather will occur.

While the storm glass will not indicate exact barometric pressure in numerical values, it is still regarded as an accurate monitor of air pressure changes. This item will arrive empty and can be filled with any color liquid desired using the included filling kit.

Galileo Galilei (1564 - 1642), an Italian physicist, mathematician, astronomer, and philosopher, played a major role in the Scientific Revolution. His findings provided the framework for Newton's laws of motion and Einstein's theory of relativity. His discovery that the density of a liquid changes in proportion to its temperature inspired the invention and explains the accuracy of the "Galileo Thermometer".

Johann Wolfgang von Goethe (1749 – 1832), a German writer and politician, influenced the likes of Nietzsche, Mozart, Beethoven, Schubert, and Brahms. Goethe was also keenly involved in studies of natural science and color theory. He developed and popularized his simple but effective "Weather Ball Barometer" using principles developed by Torricelli.

This product is a testament to the scientific principles discovered by Galileo Galilei and Johann Wolfgang von Goethe. It is a hand-crafted, optical-quality glass item that can be used both indoors and outdoors to accurately monitor ambient temperature and atmospheric pressure.
