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 and eye-catching gift items today. Thermodec transforms classic Galileo thermometers into contemporary weather pieces. Each thermometer reads temperature in Fahrenheit and Celsius, and is sure to be the conversation starter in any setting. This Galileo Thermometer is a unique-looking device filled with a special liquid and a sphere that measures the correct temperature based on a fascinating scientific principal. What Galileo discovered is that the sphere would rise or fall according to the temperature. Because the liquid in the middle contracts slightly at lower temperatures and expands at higher temperatures, the sphere will rise and fall accordingly.
