This is an example of the archimedes screw,
currently one of the objects at the Pinnacle Gallery
in Townsville of the Leonardo Da Vinci
exhibition, although not one of his inventions.
The rest here are, but this is pretty cool.
Turn this handle, here, and the turnscrew
moves the water from low lying areas to higher
ground, and is originally attributed to the
designs of Archimedes himself.
