It's a debunker's video... found via a link from Max Eberle's FB.that link is bad... its a round vs flat earth video
I have nothing to say on the other aspects of the video. Not relevant here, just some nice physics in action in the part I linked to. Though, go to the time segment I referenced to see the clip.
I'd use youtube clipping services but they seem to have problems at times.
Perhaps someone can download the short relevant part and upload and post a link. It's 1:40am where I am.
