Mini Magdeburg Hemisphere

#810 Miniature Magdeburg Hemisphere. This is a fine quality but less expensive version of the popular vacuum demonstration apparatus.  Air is forced from the disk after being placed face to face.  The disks are then very difficult to pull apart, showing the strength of air pressure.  2.5"" in diameter. Instructions provided.
