Remember how Red Bull made that amazingly ridiculous athlete-powered Rube Goldberg machine? This is how they did it. And it includes 11 athletes, 12 different machines, 4 RED cameras, 45 GoPro cameras, a 75 person crew putting in 3,422 man hours and a helluva lot of sawdust.

I'm a sucker for behind-the-scenes footage of crazy videos, and that Red Bull Rube Goldberg was definitely crazy enough. Some of the athletes were pulling off their stunts for the first time! And some of the machines weren't even cooperating! It's amazing that Adam Sadowsky and his crew at Synn Labs were able to pull this off. [YouTube]
