a word improperly defined in popular dictionaries for nearly one hundred years. a siphon refers to a tube bent in a 'u' or 'v' shape with one short leg and one long leg. siphons move liquids from one area, through the tube, to another area using gravity. the oxford english dictionary stated in 1911 that atmospheric pressure moves the liquids, which is dead wrong. its been copied by dictionary writers ever since.
dude1: clearly this siphon uses the principal of gravity to move liquid from this fish tank to this bucket.

dude2: not if you're the idiot who wrote the oxford english dictionary.
