Archimedean screw at the Long Island Children's Museum in Garden City, NY. It is comprised of a tube (similar to a vacuum cleaner hose) wound helically around an axle. The whole unit is turned by hand. If turned in one direction continously it raises water until it comes out of the top and falls back into the reservoir. If turned in the opposite direction it will lower water down the incline until the tube is empty.
