YouTuber Murmiland did come up with this epicness of a marble run. Built from wood and lots of original parts it rund about 15 meters in length – with a 2 meter special elevator and a acrylic glass tube of 5 meters lenght. Very cool construction that got over 600.000 views on YouTube.

“You are the yellow marble on the rafting track. Good luck on the dangerous track.”
