Put hemispheres precisely together so that all edges match. Pump air out of the space between hemispheres. The inner pressure highly decreases. Because of the difference in pressure the outer air pressure highly presses hemispheres together. When the air leaks again between hemispheres, hemispheres get apart again. Otto von Guericke was the first who exposed this experiment for the emperor in Magdeburg in the year 1654. Two horse teams weren’t strong enough to separate the hemispheres. This is physics experiment for science project.

The Magdeburg hemispheres are a scientific demonstration of the power of atmospheric pressure. The key points of the Magdeburg hemispheres are:

  1. The Magdeburg hemispheres were invented by the German physicist and inventor Otto von Guericke in 1654.

  2. The Magdeburg hemispheres are two metal hemispheres that are designed to fit together perfectly, creating an airtight seal.

  3. By using a vacuum pump to remove the air from inside the hemispheres, the atmospheric pressure on the outside of the hemispheres causes them to be held together with a tremendous force.

  4. This force is so great that even two teams of horses, each pulling in opposite directions, were unable to separate the hemispheres when von Guericke first demonstrated the experiment.

  5. The Magdeburg hemispheres were one of the first demonstrations of the power of atmospheric pressure and are still used today as an educational tool to teach about the principles of physics and air pressure.
