I'm a bit lazy and don't have the science-fact (numbers needed) but perhaps you could make an explanatory video on how masses (people, dogs, cars) would be sling-shot of the earth using current nature-laws such as friction, newton (yes newton) and the fact that the globe is spinning at 1040 miles an hour.
I mention common-used laws like Newton because such a video is to prove to 'globers' that their own science does not uphold them staying glued to the surface of a globe-earth.
