(Description below from Jelle’s YouTube video)
This giant marble run (or rolling ball machine) was constructed in 2011 in a little amusement park called “De Waarbeek” near Hengelo, Netherlands. It has 9 paths and a huge pinball game with 4 plungers and several scoring holes and lots of bells.
Unfortunately, this machine was destroyed by children due to lack of supervision and protection. The room wasn’t closed off properly whereby some children was sneaked in and destroyed the machine by climbing in to get some marbles. It was damaged beyond repair even before the official opening.
