      - A tube could be a part of a sextant to measure angular position. (n/t) - et - 11/22/2003 3:33:12 PM
        
        Good thinking, but there would probably be a plumb bob and some kind of marked surface under the tube. (n/t) - Tom Brosz - 11/22/2003 7:09:27 PM
        
        Not if it's a magic sextant. ;) (n/t) - et - 11/24/2003 12:58:29 AM
      - Sometimes a tube is just a tube, e.g. Venus in daylight - phil - 11/21/2003 9:08:19 PM
