Marbleocity: Chaos Mountain

Build a model of chaos in action! Use the hand crank or attach a motor (sold separately) to watch the marbles lift up, and then roll down again! It's the first Marbleocity marble machine kit to feature colorful plastic accents! Perfect for beginners; one hour build time. Triple Play models can connect to one another for bigger fun! Also works with Marbleocity Motor Kit. Ages 9+
