Galileo Galilei, the pioneer of modern physics and astronomy, never could have imagined that the remarkable thermometer he invented four centuries ago would become one of the most attractive, intriguing, eye-catching gift items available today. To look at a glass Galileo Thermometer is to behold not only an instrument that tells a surprisingly accurate temperature, but also a work of beauty and art. The Galileo Thermometer sphere is a conversation piece that leaves a lasting impression. Few other gift items meld design and concept so effortlessly. This Galileo thermometer is a delicate sphere measuring 3.25" in diameter and contains 4 miniature spheres filled with colored liquid. Each sphere has a small brass plate with a temperature graduation in both Farenheit and Celsius engraved on it. The floating spheres move up and down inside the liquid-filled cylinder depending on the outside temperature. The lowest floating sphere in the upper part of the larger sphere tells the correct temperature.
This particular model is mounted on a handsome wooden base. The form of the glass sphere allows you to view the temperature from all sides, while the minimalistic design gives it a professional air perfect for sprucing up any work or home office. Makes a great gift and conversation piece!
