Add an interesting visual element to any room with this Galileo thermometer with wood stand, now just $4.88 at WalMart! (Reg $10) This thermometer measures 7.5″ high, and has a thick, sturdy mouth-blown glass construction with solid pine wood base. Colorful, liquid filled bulbs descend and ascend with temperature changes, and it measures temperatures from 64 – 80 degrees F.
Galileo Galilei, the pioneer of modern astronomy and physics, (1564-1642), discovered that liquids change density as the temperature increases or decreases. Based on this principle, the colored glass spheres inside the glass Galileo thermometer have been precisely weighted so that they respond to temperature changes. When the temperature rises, the liquid inside the Galileo thermometer becomes less dense and the colored spheres floating inside will sink towards the bottom. When the temperature of the room cools, the process is reversed and the spheres will rise from the bottom.
