About the Contest

A Rube Goldberg Machine® is made from found or discarded household items. These contraptions come from landfill, rather than contributing to it and are essentially green machines! The Institute is proud to offer the only STEM competition in the world that requires zero cost to build and participate. Anyone, anywhere, with nothing more than a pile of junk and a great imagination can build an award-winning Rube Goldberg Machine®.
