Screwpump
The video is a short
look at the operation of a screwpump sometimes called an Archimedes'
screw. The screwpump was supposedly created by Archimedes in
the 2nd century BC. However, there are some documents that suggest
such pumps were used to move water to the upper levels of the
Hanging Gardens of Babylon which predates Archimedes by several
hundred years.
