In Jelle's Marble Runs it comes to staging. A number of 30 Steel marbles drive a distance of about 61 Meters from - including some musical points, Jumping ramps and the greatest: Glow In The Dark-Passagen. Great!
I used some remains of the Marble City (which has been dismounted). I will move to a new house within some months. In my new house i will build a new marble city. This track is a temporary project while waiting for movement. At the end of this video you see some unique marbles like baoding balls and glow in the dark marbles.
