She has presented at the American Association of Chemistry Teachers (AATC) and was an Adjunct General Chemistry Instructor at Northeast Wisconsin Technical College. tall, the Galileo Thermometer holds seven floating globes in total – with the lowest floating globe indicating the current temperature. The key is to not hold the thermometer in your hands because your hands will warm it up and give a skewed reading.
An ivory indicator determines the height that needs to be reached by the mercury in the vessel to take correct readings. For our Galileo thermometer, for any given density, some of the bubbles will float while others will sink. The Galileo thermometer works because of the principle of buoyancy, which states that objects that are denser than their surroundings sink, and objects that are less dense than their surroundings float. SCIENCE MEETS ART: The Galileo Thermometer is an example of utilizing scientific principle to create a useful artistic piece for day-to-day use. You can tell the temperature by reading the medallion on the middle floating sphere, if there are clusters of spheres at the top and the bottom of the tube, or with a few other tricks, depending on the configuration of the spheres.Under normal conditions, the orbs will settle into two groupings toward the top and bottom of the glass column as shown to the left. Each glass ball has a metal tag attached that serves to both indicate temperature and as a counterweight. Both pieces are beautifully shaped with a wooden base that makes the set easy to display on desk or bookshelf.
EXCELLENT INDOOR THERMOMETER: This Galileo Thermometer from Lily's Home makes the ideal indoor thermometer. A rising glass sphere indicates a fall in temperature, whereas a rise in temperature is indicated by a falling glass sphere. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .Sometimes a cluster of spheres floats by the top of the tube, and a cluster sinks to the bottom, while one sphere hangs in the middle. Each bubble has a metal tag attached to it that indicates temperature, which also serves as a calibrated counterweight.
Whether you're looking for a perfect gift to spruce up your friend's garden, or if you need a housewarming present, Lily's Home has something for everyone!If there is no bulb floating in the gap between the rising and sunk bulbs, use the lowest bulb from the floating cluster to get the temperature. The barometric tube is fixed to a wooden board and runs down into a vessel serving as a cistern for the barometer.

A Goethe weather ball barometer is a device that predicts barometric weather changes by observing the rise and fall of liquid within the spout of a vented glass vessel.
The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density.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.
