Science is at the heart of everything we do. It’s our inspiration and our medium. It's how the hard work gets done. How the toughest problems get solved. Our Rube Goldberg machine and its parts are inspired by this. No other company applies science like we do. Here, invisible forces — physics, thermodynamics, chemistry, energy — combine to make something visible, something truly inspiring. A 3M Brand Machine. http://www.3m.com
