The Rube Goldberg Machine Contest®

About the Contest

A Rube Goldberg Machine® is made from found or discarded household items. RGMs come from landfill, rather than contributing to them. 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®.

  • All ages
  • Compete at a live regional as a team
  • All machines must complete the annual task
  • Judged by a panel of Rube Goldberg experts
  • Prizes TBA
