Bladder Glass

Description:

This heavy glass vessel open at both ends is designed for use with an air pump. When the air is evacuated, a bladder (or hand) put over the top opening will be drawn into the vessel. The form has been used for physics demonstrations since the eighteenth century. This example came from the University of Virginia.
