The Falkirk Wheel is considered an engineering masterpiece, although it was created out of a desire to reinstate interest in the canals. It connects the Forth and Clyde Canal with the Union Canal, which were formerly connected by a series of eleven locks, dismantled in 1933.
It has a sort of mechanical beauty, I think.
You can barely see the boats in each tray.
There is also a small waterworks park, showing various types of hydro-engineering throughout history. The park is interactive- for example, the bicycle on the left powers a water geyser further up the slope.
I ran the Archimedes Screw, a device that carries water upwards with screw threads. Windsor Castle was recently modified to use two 40 tonne screws for waterpower. It was harder to get moving than I expected!
Paul ran this water geyser by tilting the pump. He got the water to shoot fairly high!
