I went through it frame by frame and what I realized after was that the foreground didn't tell me anything. Watching the background and using some logic, I realized Honda didn't have a long enough room for this
So I searched around 1 min into the movie and conclude that the most logical place is the nut falling and making the muffler roll. It's by far the easiest place to do anything with as everything's still except for the nut or w/e that thing rolling is. Anyway, almost an hour wasted, back to spring break.
