I always found this story fascinating

  >On entering the factory floor and far from the equipment, Mr. Swenson's 200KV/ft handheld electrometer was found to slam to full scale. When he attempted to walk through the corridor formed by the moving film, he was stopped about half way through by an "invisible wall." He could lean all his weight forward but was unable to pass. He observed a fly get pulled into the charged, moving plastic, and speculates that the e-fields might have been strong enough to suck in birds! i wonder what Geiger counter would show there at such potentials (youtube has videos for 3M tape unrolling generating X-rays even at lower speeds and scales)

    Would a faraday cage stop this field? I mean if you were sitting in a faraday cage on a moving conveyer belt perpendicular to the invisible wall and passed through the invisible wall, would it still have the effect or would you pass right through?

      there would be forces acting on the cage (while field inside would be pretty undisturbed). Thus the cage would probably be stopped by the field too.

    Surely this was sufficiently interesting for someone to attempt to replicate it for the purpose of entertainment?
