Product size: 110*80mm Weight: 220 grams Material: glass, paraffin oil, water Measuring temperature range: 18℃-26℃ Hand-blown glass balls show the beauty of craftsmanship, and use incredible chemical changes and phenomena as indoor furnishings, which are both beautiful and interesting. Even works of art can be used as scientific textbooks. The physicist Galileo discovered that the specific gravity of a liquid changes according to the temperature. Use that principle to make this thermometer. When the temperature is different, the density of the liquid will change, and the buoyancy will also change. Therefore, the glass float in the container will slowly rise or sink with the temperature change. The glass ball displays the temperature, and the actual temperature is read on the temperature plate floating on the upper glass ball. Precautions: 1. Please don't use it near fire and heating equipment. 2. Please do not place it in direct sunlight. 3. Do not fall heavily or rub strongly. 4. This product is broken, if the liquid inside comes in contact with the skin, please rinse immediately with clean water. If you are wearing clothes, please wash the clothes thoroughly with water.
