* Today we consider four entertaining experiences in which the steam produced by the boiling of water expels air from the vessel, and after cooling and condensation of steam, its pressure in the vessel sharply falls, and then atmospheric pressure creates real miracles. They will be looked at with great pleasure by both children and adults.

* What did you learn about atmospheric pressure today? Can you give simple examples?
