Pick a color! Will your marble win against 11 others in the Longest Sand Marble Run Ever? Made by Jelle Bakker of Jelle’s Marble Runs on a Netherlands-based sand dune, this sand track measures 230 meters (750 feet) long and features twists, turns, multiple pathways and slaloms, a small funnel, and more fun details that keep the marbles in competition for first place.
Previously from Bakker: 11,000 marbles in a Marble Tsunami marble run machine.
