World’s Largest Rube Goldberg Machine

We’ve seen plenty of Rube Goldberg machines, but this one holds the Guinness World Record for the largest one to date. Chevrolet Menlo, Wang Xiqi, and Guan Jian built the complicated contraption, which takes 427 steps to turn a light on. We’re not sure if it’s physically the largest, but it’s the most complicated we’ve seen.
