Magdeburg SpheresEntry/Object ID
2013.3.51Description
These are designed to illustrate the pressure of the air on the halves of the sphere after the inner air has been exhausted by a vacuum pump. These spheres seem to be an improvement on the earlier Hemispheres of Otho Guericke, the inventor of the air pump.
Two of the spheres can be joined in tandem, while the other rests on its own base. No name of maker.Collection
