Biggest Gravitrax Marble Run in the World with 20,000 parts!

This huge marble run is made with Ravensburger Gravitrax and contains more than 20,000 parts, over 246 meters of total track length and more than 100 action stones and marbles!

It was build in only 11 days by me (Jelle Bakker) and Jonas Lang in Galeria Kaufhof (department store) at Berlin Alexanderplatz.

This project has a lot of different paths and it was very difficult to follow all balls through this large complex. Only 3 balls will be released at the top and the "splash" parts will be used to release more balls throughout this marble run.

I only recorded the most interesting parts because of the complexity of this big marble run. The running time after one release is slightly over 3 and a half minutes! Lots of things happen at the same time which makes it very challenging to follow one ball or one part.

NOTE: This project has been dismantled and is not present anymore.

Dimensions: 7,50 meter long X 4,50 meter wide X 1,80 meter tall (including tables)
The marbles (or balls) used are 13 mm steel balls which are enclosed in the Gravitrax sets.
You can buy Gravitrax at most major toy shops. There are new sets and expansions coming in Late 2019!
