Grimm's - Assembly Set Ball Run

The children may build up this ball run by themselves, sorting the colours as their discretion.
Resulting in a double spiral run, one can also have marble races: for example, you let run a wooden bead against the included bell. Who will be the winner?
Which ball is the most quit running down the path? Which one makes the most noise? After a while, the ball run can be dissembled and arranged in a different colour set-up, so the fun starts again.
