I’m going to discuss these in reverse order, critiquing and adding missing detail. Although the video is nearly twelve minutes long, it’s light on detail, with much of the time being spent telling us how cool Lew is. This is unnecessary—we can tell how cool Lew is from his backwards baseball cap.
I love how Dr. Drang’s engineering background provides a unique perspective on alloys and heat treatment. (Also, you’ll learn how aluminum is like a ball of bread dough.) So read the story already, now that we’ve recommended it twice.
