About This Product
The two cups are placed together and the air inside is removed through the stop-cock with a vacuum pump. Atmospheric pressure then holds the cups together with a large force, and they come apart only when the stop-cock is opened to release the vacuum. The Magdeburg Hemispheres can be exported to customers in Tunisia, Iceland, the Bahamas and Zimbabwe.
