There was a movie clip here, but it appears to have been removed. There'll be copies out there someplace.

EDIT: view the demo film here... CAUTION: Viewer descretion is advised, not that any chickens are harmed it seems..well, they remain alive anyway. It would surely feel like being sucked up by a Dyson! It is so wrong.
