Jelle Bakker is soon starting to build a spacewarp marble run (Kugelbahn) in Explorion, Heerlen.
He will use 11 mm steel balls and tracks of the spacewarp-system. The 200 m long marble run will show spiral funnels, loops, corkscrews, electronic contact units triggered by the balls, elevator systems and many more.
The project will be open for public at July 2010.
