Madeberg Hemisphere - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

Exhibition items use mechanical interaction to learn about the Marburg Hemisphere Experiment and experience atmospheric pressure. The exhibition items consist of a Magdeburg hemisphere model, an exhaust system, display racks, and more. When participating, close the hemispherical dome to the top, press the "start" button, and the vacuum pump will create a vacuum inside the sphere. Then grip the handle tightly and pull it down to try to separate the sphere. After a period of interaction, the two hemispheres automatically separate. The Marburg Hemisphere experiment proves that atmospheric pressure exists and is very strong. In the experiment, the air in both hemispheres was extracted to reduce the number of air particles inside the spheres. The atmosphere outside the sphere tightly compresses the two hemispheres together, making it difficult to separate. Operation method: 1. Pull down the rope to allow the hemisphere to engage with the top; 2. Wait for a vacuum to form inside the sphere; 3. Try pulling the handle of the hemisphere to see if it can be pulled apart; 4. Think about the principles behind it.
