When von Guericke pumped the air from between them, they were forced together by the external pressure of the atmosphere. This force was so strong that two teams of eight horses could not pull the hemispheres apart. When the vacuum was released they came apart easily. The experiment was conducted in the 1650s in Magdeburg, Germany. Otto von Guericke (November 30, 1602 - May 21, 1686) was a German scientist, inventor, and politician. His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion, and his advocacy of the reality of action at a distance"and of absolute space. Around 1650 von Guericke invented a vacuum pump consisting of a piston and an air gun cylinder wi...
