Ignore the fact that its an advert for Red Bull and bask in this athlete powered Rube Goldberg machine. I just love Rube Goldberg machines, what a pointless entity but at the same time so beautiful. This one was created by Adam Sadowsky of Syyn Labs for Red Bull, the course took 100 workers over 17 days and 25 tonnes of material to build. Each level had weights, bowling balls, chainsaws and, of course, extreme sports. Go give it a watch!
