![This Is the World's Most Extreme Rube Goldberg Machine [VIDEO]](https://helios-i.mashable.com/imagery/archives/06cuDePfzTAfXEtNxdIoBYX/hero-image.fill.size_1248x702.v1647021644.jpg)
Even Rube Goldberg himself would've likely been blown away by Red Bull's latest extreme stunt.
Red Bull Kluge is an obstacle-course-like contraption run by some of the world's greatest athletes -- including Olympic hurdler Lolo Jones, skater Ryan Sheckler and Scottish trials cyclist Danny MacAskill.
More than 25 tons of material was used to create Kluge -- derived from the German word "Klug," which means "clever." The entire stunt took more than 100 builders and 17 days to complete.
Red Bull Stratos, the company's previous extreme stunt, broke a number of records in October when skydiver Felix Baumgartner jumped from the middle of the earth’s stratosphere.
