Guinness crowns Purdue Rube Goldberg machine ’World’s Largest’

The Guinness World Records designated a 300-step Rube Goldberg machine built by Purdue University students as the largest in the world. The Purdue Society of Professional Engineers and the Hispanic Society of Professional Engineers invested more than 5,000 total hours to build the innovative behemoth that flawlessly performed the assigned task of inflating and popping a balloon at the site of this year’s Rube Goldberg Machine Contest intercollegiate national championship.
