Features:
The Galileo thermometer is composed of a drop-shaped glass bottle and a brightly colored glass floating ball.
Hand-blown glass balls show the beauty of craftsmanship, and use incredible chemical changes and phenomena as indoor furnishings, which are both beautiful and interesting. Even works of art can be used as scientific textbooks.
The physicist Galileo discovered that the specific gravity of a liquid changes according to the temperature. Use that principle to make this thermometer. When the temperature is different, the density of the liquid will change, and the buoyancy will also change. Therefore, the glass float in the container will slowly rise or sink with the temperature change. The glass ball displays the temperature, and the actual temperature is read on the temperature plate floating on the upper glass ball.
