This is a video of an impressively long stainless steel marble maze (presumably designed to settle disputes once and for all) using two wooden marbles, a red and a green. It’s a real nail-biter, and there are numerous obstacles the balls run into on their way to the finish line to ensure the race is fair and entirely chance-based. Still, I wonder what the percentage win is for each track. Is it truly random? Nothing is truly random — take our meeting for example. To you it might have seemed random, but in reality I planned it months in advance. “But why?” Wouldn’t you like to know!

Thanks to my dad, who agrees if you consent to settle your dispute by marble maze, there’s no arguing with the results.
