With the Fischertechnik Dynamic Set XXL, you'll experience a marble run like never before. The marble run is 86 cm high and has a track length of 5.6 m. The marbles roll down faster than they ever have! This marble run is fully motorized and you can assemble it with the clear instructions. The marble run transports the marbles upwards with a motor-driven wheel, then they zigzag up to the top with the conveyor belt. Once at the top on the launch platform, the marbles shoot down at high speed and wind their way through 90-degree turns, quarterpipes, exchange crossovers, and many more different tracks. This set also includes 2 rainbow LED lights that make the marble run look absolutely dazzling. The contents of this Fischertechnik Dynamic Set XXL consist of 1360 marble run parts, a mini motor, 2x rainbow LED, a battery holder for the 9V battery (battery not included), and instructions.
