Marble run machine with 11,000 marbles

This marble run is at a playground called Monkey Town in the Netherlands. The creator says it has "4 tipping containers which can release up to 10,000 marbles in one go! If the biggest 2 containers (with 1000 and 10,000 marbles) are tipping at the same time, it creates a flood of 11,000 marbles!"
