I really love well made Rube Goldberg machines! This one uploaded by the Guiness World Record channel on YouTube is the world’s largest one and needs about four minutes and 412 individual steps to turn on the christmas lights. Well done!
“To make the act of switching on the town’s Christmas tree lights even more exiting, Latvian e-commerce company Scandiweb constructed the world’s Largest Rube Goldberg for the people of Riga.”
