Principles of Operation:

This apparatus is also known as a Florence Siphon. When heat energy is applied to a liquid the molecules of the liquid begin to vibrate and move faster. The motion of the molecules colliding with each other and the sides of the container produces a pressure. This pressure pushes the boiling water out of the flask through the tubing and into the beaker containing the coffee grounds. Once the heat source is removed from the boiling flask the remaining air and water molecules begin to cool and contract creating a vacuum in the flask. It is this vacuum that draws (siphons) the now brewed coffee back through the tubing and into the boiling flask.
