What Makes It Uncommon

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.

WARNING: CHOKING HAZARD – Small parts. Not for children under 3 years.

My Great-Grandkids Love This

This was a Christmas gift for a 10-year-old boy. He is one of eight siblings, and several of them have all enjoyed playing with it. The quality is very good, the materials sturdy. It will stand up well to lots of play time.

BUY! BUY!

I bought this item for my grandson. He and his family had moved out of state just a month earlier, so I knew I wouldn't see him open the gift and was sad about that. BUT….. Christmas morning, Leo opened this, and was SOOO excited. (According to Mom). He began playing with it right away and hours later still loving it. Wish I could give a more detailed description of exactly what he loves about it, but what I do know is that Leo is all about marble runs, dominoe trains and card pyramids, so this was the absolute perfect gift for him . Thank you so much for the unique and Uncommon gift ideas. I Love Uncommon Goods!
