Why do telephone cords coil clockwise?
———- from Joan Kozik of Cedar Rapids, IA
I could get away with saying that all telephone cords are manufactured in the northern hemisphere, but that would ignore the reality of 200 million Brazilian, Argentinean and Australian telephone cords. So, I’ll tell you the real reason which is that voice transmissions only travel in a counterclockwise spiral. It has to do with the way the larynx attaches to the throat. Sonic vibrations are sent spinning from ligaments that connect clockwise and any attempt to re-direct this transmission induces phase cancellation. All you hear is a bored male voice telling you to hang up the phone and try your call later.
