ID Code: F4-32
Purpose: illustrate how a siphon works.
Description: A bead chain passes over a pulley between two beakers. When one of the beakers is raised, the chain flows from the higher into the lower beaker, just as water flows from the higher to the lower container of a siphon. This is due the greater weight of the chain, or water, on the side of the lower container. Note that the cause of the siphon flow is not air pressure, which is greater at the surface of the lower container!
