In the last century, the cartoonist Rube Goldberg entertained and fascinated readers with his humorous cartoons of truly complicated devices or procedures that resulted in some simple task being completed. This film follows his lead and shows for some 30 minutes, using simple machines (levers, inclined planes) and fire, a series of continuous actions which accomplish nothing in particular except to entertain the viewer. No humans are shown in the film, though their work in setting up the event, apparently in a large warehouse, is evident in how smoothly, more or less, the whole crazy enterprise takes place. There is a certain underlying humor to the whole thing and also the anticipation of how the film makers will manage to keep the movement going. Bravo.
