So I'm sure most people have seen the infomercials for the Laser Level that you stick on a wall to help you hang pictures, or whatever. Towards the end of the commercial they say its beam even goes around corners. Anyone have one? How can a laser beam go around a corner without a mirror? Edit: It's called the Laser Level, not Laser Light :b This story says it can only go "around" inside corners, not outside corners which makes sense. But I'm pretty sure I remember the commercial showing it around an outside corner because there was a lightswitch on each side.
