- The definition of a siphon is a tube that is used to draw liquid from one container into another, lower container by atmospheric pressure and gravity.
An example of a siphon is a tube where gas is forced out of a gas tank into a gas container on the ground.
- To siphon is to run a tube from one container to another in a way that uses atmospheric pressure to move the liquid into the lower container.
When you hook up a tube to a gas tank and then use atmospheric pressure to move the gas out of that tank into a gas canister below it, this is an example of a time when you siphon.
