Watch VoirFilms. 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.
