Junior Chain Reaction Construction Set

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.
• For ages 5+, with adult assistance recommended for younger learners.
• Made in China.

As kids master this set, they can level up to our Musical Chain Reaction or Racecar Chain Reaction kits, with even more intricate builds and challenges.
