Product Description Gift Essentials Galileo Thermometers

Inside the thick, sturdy glass tube, colorful glass bulbs descend and ascend with temperature changes. The lowest floating bulb indicates the ambient temperature and liquid magnifies temperature readings. Galileo\'s glass thermometer does not require batteries or a power source. The thermometer works on the principles of buoyancy and density. Galileo Thermometers make a beautiful gift for home or office.

How it Works

Galileo discovered that the density of a liquid changes with temperature. For most liquids, as temperatures increase, density decreases. By putting precisely weighted objects in the liquid Galileo was able to observe the objects floating and sinking to different depths at different temperatures.

Appreciating the Galileo Thermometer

Galileo Thermometers are intended for indoor use. When choosing the best location indoors, keep it out of direct sunlight. Each bulb inside the Galileo Thermometer represents a temperature, as indicated by the metal hang tag beneath each bulb. The temperature can be read by locating the sphere that is floating nearest the middle of the tube and reading the tag. If there is a cluster near the top of the tube, and a cluster near the bottom, the temperature is an average of the lowest sphere in the top cluster and the highest sphere in the bottom cluster.
