Water flows! By turning the Archimedean screw, water will flow uphill. The device can be combined with water park tracks to make a closed water circuit, so that the water will flow continuously with no need to add any more water.

The struts offer all sorts of possibilities, from making water run above small valleys to constructing a fantastic descent down to a flat area. Lots of fun with your experiments!
