Product Description
15 inch Multicolor Spheres and Numeric Temperature Tags: Home & Kitchen. What Galileo discovered is that spheres of different weights would rise or fall according to the temperature. 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 eyecatching gift items today. The Galileo Thermometer is a glass cylinder filled with colorful spheres that measure the correct temperature based on a fascinating scientific principle. Because the liquid in the cylinder contracts slightly at lower temperatures and expands at higher temperatures, the spheres rise and fall accordingly.
