What is the difference between a gravity feed and a siphon feed?
A gravity feed is using gravity to move objects from one point to another while the siphon feed involves the transfer of liquid from a higher ground to a lower with the use of tubes. In the gravity feed any matter can be moved while in the siphon feed the only thing that can be moved should be in liquid form.
For the carbonation device, see soda siphon.
The word siphon (from pipe, tube, also called syphon) is sometimes used to refer to a wide variety of devices that involve the flow of liquids through tubes...
