The Storm Glass is hand blown and accurately forecasts changes in weather hours in advance. The Storm Glass, or Goethe Barometer, is regarded as the oldest barometer in the world. Although Johan Wolfgang von Goethe is sometimes credited with its invention as one was found in his bedroom after his death, there is evidence that the Moors used similar instruments during the 8th century. Also called Thunder Glasses, historians believe the early settlers sailed to the Americas using this rudimentary barometer.
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 Galileo Glass Thermometer have been precisely weighted so that they respond to temperature changes. When the temperature rises, the liquid inside the Galileo indoor 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.
