The Magdeburg hemispheres were two bronze hemispheres made by Otto von Guericke in 1754, one of which had stopcock. After the rims of these had been placed together with a greased leather ring in between to form an airtight joint the air was pumped out and the stopcock closed. Before this was done the hemispheres could be pulled apart quite easily, since the pressure outside was balanced by an equal pressure inside. On removal of the air from inside, only the external atmospheric pressure acted and pressed the hemispheres tightly together. This experiment was first performed before the Imperial Court assembled at Ratisbon, on which occasion two teams of eight horses each were harnessed to the hemispheres and driven in opposite directions. They proved unable to separate the hemispheres until air had been readmitted through the stopcock.
