Minimalist Galileo Thermometer - 37cm

This is a thermometer with a transparent and minimalist design. Inside a cylindrical glass tube are glass spheres of varying densities. As the temperature changes, the transparent spheres float up and down within the tube, making it both an artistic display piece and a vessel of scientific wonder. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_33188361-397c-44f8-90cc-a422a32814bc.jpg The Galileo thermometer utilizes Archimedes' principle of buoyancy. The liquid inside the glass cylinder is highly sensitive to temperature changes. It contains five transparent, gourd-shaped glass balls, each with a small copper tag indicating a temperature, ranging from 26°C, 24°C, 22°C, 20°C, and 18°C. If the ambient temperature is lower than the temperature indicated on a ball's tag, that ball will float to the top of the glass tube. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_6348f522-6114-48ee-b083-8edd3f780497.jpg The Galileo thermometer is an exquisite glass ornament that combines science and craftsmanship, offering practical functionality. Beyond displaying the current temperature, it makes an excellent gift or collectible. You can even use it for experiments to add a fun element to your daily life. Place the thermometer in a basin of cold or hot water to observe the movement of the transparent spheres! <Science Fun Fact> A Galileo thermometer is a thermometer composed of a glass cylinder, a transparent liquid, and weights of varying densities. As the temperature changes, the density of the liquid also changes, causing the suspended weights to move up and down until they reach a density equal to that of the surrounding liquid. The weight with the lowest density will be at the top, and the one with the highest density will be at the bottom. Each weight is adorned with a metal disc engraved with a number. To read the ambient temperature, find the weight that is floating at the very bottom, just below the top.
