Pascal Vases (3)
Pascal Vases (3)
- The fact that a liquid poured into several communicating vases, whatever their shape, will seek the same level in each, was known in antiquity. It became scientific when the French savant, Blaise Pascal, discussed it in his Treatise on the Equilibrium of Liquids (1653). In time, simple hydrostatic instruments became popular for classroom demonstrations, and these instruments became known as Pascal vases. These three glass vessels of different sizes and shapes, with a threaded collar of brass at the lower part of each, were made for that purpose.
