Product Details
Galileo Galilei discovered that when a liquid's temperature increases, its density decreases, which inspired the creation of these unique thermometers featuring colorful spheres that rise and fall to indicate temperature. Each decorative and functional thermometer is housed in a sealed glass cylinder filled with a clear liquid and contains several glass spheres of varying densities. The tag on the lowest sphere in the top group indicates the current temperature, making it an engaging conversation piece suitable for both home and office environments.
