Bill Hammack, the engineerguy, explains the engineering behind your typical soda bottle, as well as juice and sports drink bottles. It’s a direct sequel to The Ingenious Design of the Aluminum Beverage Can.

Hammack is a Grainger Distinguished Chair at the University of Illinois — Urbana-Champaign. It might be cool if he did something like this for Illinois sports. Don’t you want to learn the engineering behind a golf ball or throwing a spiral? The videos could be played during timeouts or pre-game.
