Wonder why somebody would make such a video in the first place? There was no way for those AA to produce 6 volts and just spill out like that. The outer case of each was bare, none were wired or welded, and all oriented in the same direction. Guess it would fool some people, but why? Suppose it sort of like releasing a computer virus. Wonder if that brand 6 volt battery even exists, or if he made his own label for this video project.
I've been off the throw away batteries for years now, just an occasional 9 volt for the alarm clock, and caller-ID box.
