Fountain in Vacuo
notes: label: Description
content: A Fountain in Vacuo (or Vacuum Fountain) consists of a hollow glass vessel with a long stem fitted with a stop cock. When the air is removed from the vessel, the cock is closed; if the bottom is then put into a pail water and the cock opened, the result is a jet of water as in a fountain. Pieter van Musschenbroek (1692-1761), the Dutch scientist best known for having invented the Leyden jar, described the form.
