Jelle Bakker, who has a fondness for complex marble runs, made this epic 750-feet long sand track that descends some 125 feet from its start to its finish. The 12 marbles competing in this video take almost four-and-a-half minutes to complete the run, and you’ll be surprised to find yourself rooting for your favorite.
