The Magdeburg hemispheres were invented in 1650 by Otto von Guericke,a scientist and the mayor of Magdeburg. He used them to demonstrate the concept of air pressure. When two hemispheres were placed together and the air was pumped out from the space between them,16-30 horses could not separate them. This spectacular experiment was demonstrated to the astonished audiences on several occasions. Photographed here is a replica of the Magdeburg hemispheres on display at the Deutsches Museum,Munich,Germany | |
