==Origin==
French ''siphon'', from Latin ''siphon''-, ''sipho'' tube, pipe, siphon, from Greek ''siphōn''
*[http://en.wikipedia.org/wiki/17th_century 1659]
==Definitions==
*1a : a tube bent to form two legs of unequal length by which a [[liquid]] can be transferred to a lower level over an [[intermediate]] elevation by the [[pressure]] of the [[atmosphere]] in forcing the liquid up the shorter branch of the tube immersed in it while the excess of [[weight]] of the [[liquid]] in the longer branch when once filled causes a [[continuous]] [[flow]]
:b usually syphon : a bottle for holding aerated water that is driven out through a bent tube in its neck by the [[pressure]] of the [[gas]] when a valve in the tube is opened
*2: any of various tubular organs in [[animals]] and especially [http://en.wikipedia.org/wiki/Mollusk mollusks] or [http://en.wikipedia.org/wiki/Arthropods arthropods] that are used for drawing in or ejecting [[fluid]]s.
==Description==
The word '''siphon''' (Greek: Σίφων, also spelled ''syphon'') is sometimes used to refer to a wide [[variety]] of devices that involve the [[flow]] of liquids through tubes. But in the [[English]] language today, the [[word]] siphon usually refers to a tube in an inverted U shape which causes a [[liquid]] to flow uphill, above the [[surface]] of the [[reservoir]], without pumps, powered by the fall of the liquid as it flows down the tube under the pull of [[gravity]], and is discharged at a level lower than the [[surface]] of the reservoir. In [[practical]] siphons, [[atmospheric]] [[pressure]] pushes the liquid up the tube into the region of reduced pressure at the top of the tube. The reduced pressure is caused by [[liquid]] falling on the exit side. In the [[laboratory]], some siphons have been [[demonstrated]] to work in a vacuum, indicating the [http://en.wikipedia.org/wiki/Tensile_strength tensile strength] of the liquid is contributing to the operation of siphons at very low [[pressures]].
