Minimalist Galileo Transparent Thermometer-37cm

This is a transparent and minimalist design thermometer. The cylindrical glass tube is equipped with transparent glass balls with different densities. With the temperature, the transparent balls will float up and down in the glass tube. It is not only a work of art, but also a scientific mystery floating in it. in. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_33188361-397c-44f8-90cc-a422a32814bc.jpg The Galileo thermometer uses the Archimedes buoyancy principle. The glass cylinder contains a liquid that is very sensitive to temperature. There are five transparent gourd-shaped glass balls, and each ball is hung with a small bronze plate engraved with temperature, which is 26 degrees, 24 degrees, 22 degrees, 20 degrees and 18 degrees Celsius. If the temperature is lower than the temperature written on the bronze glass ball, the ball will float and rise to the top of the glass tube. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_6348f522-6114-48ee-b083-8edd3f780497.jpg Galileo thermometers are exquisite glass decorations that combine science and craftsmanship, and are quite practical. In addition to knowing the current temperature, they are also very suitable for gifts or collections. It can even be used as an experiment to add fun to life. Place the thermometer in the cold/hot water tank and observe the changes in the up and down movement of the transparent glass ball inside! <Science Tips> Galileo thermometer (English: Galileo thermometer) is a thermometer composed of glass cylinder, transparent liquid and weights of different densities. When the temperature changes, the density of the liquid will change accordingly, causing the suspended weight to move up and down until it is equal to the density of the surrounding liquid. The weight with the lowest density will be at the top and the highest at the bottom. Each heavy object is hung with a metal disk engraved with a number. When reading the surrounding temperature, look for the heavy object floating on the top and bottom end.
