A siphon is a tube used to transfer liquid from one container to another, often when the two containers are at different heights. The liquid flows through the tube due to the force of gravity. To use a siphon, first place one end of the tube in the liquid in the higher container. Then, suck on the other end of the tube to create a vacuum. This will cause the liquid to flow through the tube and into the lower container.
Siphons are a useful tool for a variety of tasks, such as transferring gasoline from a car to a gas can, or draining water from a flooded basement. They are also used in some scientific experiments.
