The Rube-a-Thon Contest®

How does a Rube-A-Thon Contest® work?

A reboot of the traditional Rube Goldberg Machine Contest, the Rube-A-Thon is a one-day, turn-key competition! Design, build, and run your Rube Goldberg Machine at this fun, fast-paced STEAM event.

Students arrive at the competition site with nothing more than the will to compete and a great imagination! The Contest Host provides all the building materials, costumes, and task elements to create a working Rube Goldberg Machine that completes the national RGMC task for that year.

Teams will compete in three Divisions, each with a different set time and buildable footprint.

During this day-long event, the Rube-A-Thon will also have non-competitive activities for families and other spectators. This will include a maker space with different arts and crafts activities and mini-challenges.
