Following and serving as the implied future of the opening scenes that culminated with a hominid's throwing into the sky of a bone that has been imbued with the function of a mortal weapon, now ages into the future, first the airship and then within it, a writing pen, (in a subtle reciprocal to the hominid's violent gesture), is let go by the relaxed arm of a sleeping scientist into gravity-defying floatation.
To achieve the effect of zero gravity, the pen was adhered to a sheet of glass with double sided tape, and rotated in front of the camera until the flight attendant mimics "catching" it by gently pulling it off.
