So... it is fake? My bet is on video editing for that bit of magic.

So why post a video like this? It is fun in the same way that the Bruce Lee nunchuck table tennis video was fun. But also because I think it would be awesome if someone were to actually pull this shit off... and I'm willing to bet that people will start trying. Break.com is about to be filled with tennis balls to the face.
