I have seen this episode (under different titles ) at least 3/4 times and the same background scenes, I just wish they would show daylight scenes when they are supposed to be filming during daylight hours---& dark background scenes when doing experiments during the night, not the other way round. Also if the background content had at least something to do with what the narrator was talking about. It is also very annoying that the narrator is always the same person, and yet he cannot remember their names sometimes, so to keep us watching he improvises and mispronounces their names that he pronounced perfectly in the last episode.
