That *was* pretty cool when he stood on it at the end. That's very impressive getting all those loose rocks to stay in place. That being said, I'm sure if he stood on it long enough, that thing was going down. It looked like it was seconds away from buckling.

  Some people are better at it than others. Like Devin at Smarter Every Day who has that childlike awe when he’s describing stuff that draws you in as a viewer even when you don’t really understand what he’s talking about.
