      Hi,

      I know there was a car from Marklin to measure the steepness of a hill
      but I also saw one that someone had made out of a yellow bubble thingy
      from a level (highly technical term...yellow bubble thingy) Anyway, I
      was wondering if anyone here has made one of these and how they did it?
