The document summarizes the history and operation of the Falkirk Wheel, a rotating boat lift in Scotland. It connects two historic canals that were originally joined by 11 locks. In 2002, construction finished on the Falkirk Wheel, which replaces the locks and saves time and energy by rotating boats between the upper and lower canals. The Wheel has two arms that form huge water-filled tubs, and it takes just 15 minutes to rotate the tubs 180 degrees and transport boats between the canal levels.
