When I say the above video about why soda cans are shaped the way they are is mesmerizing, I am not playing with your heart. I mean it. It is fascinating, strange, and makes a strong case for going back to school to study engineering. This video answers all your questions you never knew you had. Like, what's with that dome at the bottom of a can? Why don't you need a can-opener to open cans? It'll also make you appreciate the hell out of pull-tabs in a way you never thought possible.
Don't just take our word for it. This mesmerizing video has even got YouTube commenters in awe.
