Galileo discovered centuries ago that a liquids density varies with temperature. These works of scientific art contain colored glass temperature indicator spheres calibrated to within a fraction of a gram to measure indoor temperature accurately. The balls float in a clear liquid, changing position with fluctuations in temperature. The lowest floating sphere indicates the current temperature. We offer four different models, ranging in size from 11 to an impressive 24.
