Description
A set of magdeburg spheres, hemispheres in good condition, late 19th century
The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. They were used to demonstrate the power of atmospheric pressure. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of horses in a famous first public demonstration in 1654. The Magdeburg hemispheres were invented by German scientist and mayor of Magdeburg,Otto von Guericke
