Details of the thermometer were published in the Saggi di naturali esperienze fatte nell'Academia del Cimento sotto la protezione del Serenissimo Principe Leopoldo di Toscana e descritte dal segretario di essa Accademia (1666), the academy's main publication.

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. She has presented at the American Association of Chemistry Teachers (AATC) and was an Adjunct General Chemistry Instructor at Northeast Wisconsin Technical College. The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. When the temperature rises, the liquid inside the Galileo thermometer becomes less dense and the colored spheres floating inside will sink towards the bottom.Anne was published in the Journal of Chemical Education as a Co-Author, has an article in ChemEdX, and has presented twice and was published with the AACT. 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. These floating balls sink or float inside the surrounding water over time and temperature ever so slowly and gracefully. Based on a thermoscope created by Galileo Galilei in very early 1600s, the Galileo thermometer was not invented by him, but rather named after him by the group of academics that invented it. The blue and yellow bubbles (60 and 65 degrees, respectively) are calibrated so that they have higher densities than the water at this temperature, so they sink.

As the temperature changes, these orbs rise and fall to indicate the current ambient temperature (within the range of 64˚F - 80˚F). For our Galileo thermometer, for any given density, some of the bubbles will float while others will sink. We are currently unable to deliver to EU addresses due to the high and unpredictable costs, customs charges, and courier handling fees. This is just what I was looking for in my barn apartment in the woods :) Just wish the thermometer, barometer and hygrometer could measure outdoors rather than indoors.
