Junior inventors, assemble! This colorful chain-reaction kit brings action and reaction to life through trial and error. Designed for budding engineers (perhaps with a little grown-up help), it’s the perfect playground for learning patience and problem-solving skills. With multiple build configurations—or the freedom to design their own—kids can create, test, and refine their very own Rube Goldberg–style masterpiece.

  • Encourages trial and error while teaching kids about cause and effect through fun, hands-on play.
  • Features a colorful set of components to design creative chain-reaction tracks.
  • A wonderful introduction to engineering and physics that fosters creativity and patience.
