Archimedes Screw.

An Archimedes screw was one of the first types of water delivery to be invented. It is a kind of pump that you use when you need to get water from the bottom of a hill to the top. The Archimedes screw was first invented by the Greek mathematician and inventor Archimedes in the year 250 (BC).

The Archimedes screw was also one of the first types of irrigation in Egypt. Tales say it was used to pump water out of the King's ship in the 3rd century.

After electricity was invented the Archimedes screw was used less and less until only about a quarter of the worlds population used it.

Pictured below are some Archimedes Screws.
