Through his experiments, Galileo discovered that liquids change density as the temperature increases or decreases. Galileo Thermometer How it Works A large glass tube is filled with clear liquid. Floating inside the tube are seven small glass bulbs. The bulbs are calibrated by filling them with precise amounts of colored liquid so that they have a specific density relative to the clear liquid in the main tube (some bulbs are calibrated to be higher in density and some are lower). Finally, metal tags that serve as counter weights are hung from each bulb. A temperature is engraved on each tag. When temperature rises, the liquid inside the glass thermometer tube becomes less dense and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the tube becomes denser and the liquid-filled bulbs will float. Since the bulbs are different density, some will sink or float more than others. It's not just a decorative thermometer, it actually works! Each bulb inside the Galileo Thermometer represents a temperature, as indicated by the metal hang tags beneath each bulb. The temperature is determined by the lowest floating bulb in the thermometer. When a bulb is seen floating in the middle of the tube, the temperature reading is between that bulb and the lowest floating bulb at the top of the tube. If all the bulbs float to the top, the temperature is less than the lowest floating bulb. If all the bulbs sink, the temperature is above the highest bulb. Return Policy Payment Shipping © 2017.
