Magdeberg Hemispheres

An interesting piece of science equipment, believed to date from the 19th Century. First invented in the 1600s, it is used to create a vacuum and demonstrate atmospheric pressure. These are likely to have been kept in schools or universities to demonstrate to students. 

The two parts are made of heavy brass with a metal lining. They are in good condition for their age with no damages. The brass has tarnished and slightly pitted over time but overall they display very nicely. 

Approximate Measurements: 

Total Length together : 9 1/2" (24cm)

Diameter : 3 3/4" (9.5cm)

I see no reason why it shouldn't work as intended but I have not tested it and it is being sold as a collectors item rather than a working scientific instrument. The best description comes from the photos so please look at them all carefully and if you have any questions please ask
