Description

Invented by Benjamin Franklin (1706-90), an American politician and natural philosopher in 1768, this object is known as a pulse glass. The magenta coloured liquid is sealed in the glass, creating a vacuum. When one of the glass balls is held in a person's hand, the liquid boils. Franklin viewed his invention as an intellectual curiosity. maker: Unknown maker Place made: Europe
