TFA Dostmann Galileo Galilei termómetro de líquido, vidrio multicolor, 18-26 °C, de pie 18.1017.01.54

Place this Galileo Galilei liquid thermometer on a desk or shelf to observe temperature through the rise and fall of five multi-coloured glass spheres. Each sphere carries a metal tag marked in 2°C increments from 18°C to 26°C, floating in a clear liquid inside a cylindrical glass tube. As room temperature changes, the spheres move according to the principle of density, making it both a decorative piece and a functional indoor thermometer.
