I have a quick question about this ananova article that's been bothering me. I can't figure out any way it makes sense. (and ananova usually doesn't publish complete bs as far as I know) http://www.ananova.com/news/story/sm_3148241.html [Broken] basically, my question is: does it make sense to you? how is there voltage through a single chunk of metal? or is there something special about a burglar-proof door, like two separate panels or something? but then why wouldn't it just discharge completely when they connect a wire to the two sides? What am I missing?
