Wallace and Gromit try out ten of their latest inventions—which rarely work as planned.

Artists Peter Fischli and David Weiss create the ultimate Rube Goldberg machine. The pair used found objects to construct a complex, interdependent contraption in an empty warehouse. When set in motion, a domino-like chain reaction ripples through the complex of imaginative devices. Fire, water, the laws of gravity, and chemistry determine the life-cycle of the objects. The process reveals a story concerning cause and effect, mechanism and art, and improbability and precision, in an extended science project that will mesmerize the mind.
