A Deep Dive on Aluminum Can Design and Manufacturing

Bill Hammack goes by the moniker engineerguy on YouTube, and he's been making entertaining engineering videos for five years. In his most recent effort, he spends a little over 10 minutes explaining the engineering of aluminum beverage cans. And it's fascinating.

Hammack manages to take a seemingly pedestrian object and explain why the engineering behind it is so vital—how it's made, why it's made that way (for instance, why there's a dome on the bottom), and what advantages the design has over other options. There's even a brief history lesson showing aluminum cans of yore, including vintage pull-tab cans.

I guarantee that you've never seen an explanation of a soda can as entertaining as this. Hammack is like Mr. Wizard, but not grumpy. Enjoy:

Most impressive fact: "The aluminum can industry produces over 100,000,000,000 (100 billion) cans per year." Wow.
