The Galileo Thermometer is a unique-looking cylinder filled with colorful spheres that float in a special liquid and measure the correct temperature based on a fascinating scientific principal. Galileo discovered that spheres of different weights would rise or fall according to the temperature. Because the liquid in the cylinder contracts slightly at lower temperatures and expands slightly at higher temperatures, the spheres rise and fall accordingly. In a Galileo Thermometer, the lowest floating sphere in the upper part of the cylinder tells the correct temperature.
