Take a marble-powered tour of the capital with the ROKR London marble run. Assemble 431 laser-cut pieces into a compact cityscape where a USB-C powered motor lifts steel marbles to loop continuously through London Eye, Big Ben and Tower Bridge. Expect around 5 hours at difficulty ★★★★☆, making it an absorbing project for teens and adults who enjoy mechanical builds. Parts press-fit via mortise-and-tenon joints, perfect for a bookshelf display. Recommended Ages 12+ due to small parts and complexity.
Notes: Runs on 5V–1A USB-C power; Type-C cable not included. Wax may be excluded by customs (any candle/beeswax works for smoothing gears).
