Anne has a BS in Chemistry from the University of Wisconsin, Oshkosh, and an MA in Secondary Education and Teaching from Viterbo University. The temperature surrounding the thermometer will make the liquid in the thermometer more dense as it cools, or less dense as it heats up. The Galileo thermometer, invented by astronomer Galileo Galilei, works mainly on the buoyancy principle.
New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. Features an 11-inch Galileo thermometer, a glass Goethe barometer with frosted world map decoration and a wooden base. As the temperature of the water rises or falls, the liquid will either expand or contract, respectively, varying the density in the process as well.
Full a big beaker with water that’s either colder or warmer than the ambient temperature of the room. Our distinctive ornamental (but functional) thermometers utilise 17th century astronomer Galileo Galilei's discovery that the density of liquids varies with temperature. The barometric tube is fixed to a wooden board and runs down into a vessel serving as a cistern for the barometer. This fairly accurate instrument is based on the thermoscope invented by Galileo Galilei in the early 17th century.
Affixed to each sphere is a little metal tag that has a temperature level on it in increments of 2 degrees. The Galileo thermometer is certainly not the most precise instrument in the world but it is certainly clever.

SCIENCE MEETS ART: The Galileo Thermometer is an example of utilizing scientific principle to create a useful artistic piece for day-to-day use. Based on this principle, the colored glass spheres inside the glass Galileo thermometer have been precisely weighted so that they respond to temperature changes. This can fade the color of the spheres inside the tube, affecting its temperature measuring accuracy. Under normal conditions, the orbs will settle into two groupings toward the top and bottom of the glass column as shown to the left.This item is finished with a hand process that creates a varying finished height, which may be slightly higher or shorter than the stated height. This temperature thermometer will make a fantastic novelty gift for a loved one or the most perfect housewarming gift and will also look great as a desk gadget.
