The video is a concept video, not a real-life recording.. it's CG. But you're asking about real-world physics. And everyone else is talking about it too, as if the video actually happened, even though it's just a CG animation.
I'm just really confused; sorry. Heh. I know I'm missing something obvious here -- figured I'd ask what it was, even though I look silly. :)
