K'NEX Marble Run 3 Model Building Set (with Motor)

This K'NEX Marble Run building set packs 504 pieces and a battery-powered motor into one box. Builders put together a working marble coaster with 11 feet of spiralling track.

Three build levels are included. Start with the beginner model, move up to the medium one, then take on the big "Wow" build once confidence grows. Standout parts include three accordion tubes, a see-saw marble scoop and a bank shot bounce pad. Hook the coaster up to the motor and the marbles keep moving for chain reaction fun.
