We interact with so many aluminum cans a day, we forget how amazing they are. Trillions are produced a year, and how often do you see them fail on their own?
The video after the jump looks at the engineering and design magic behind the can. It's almost 15 minutes, sure, but it's one of the most interesting 15 minutes you can spend thanks to University of Illinois Professor Bill Hammack, known as the engineeringguy on YouTube. Where are cans shaped the way they are? When did tabs become a thing? And how are they so strong?
All these questions are answered after the jump.
