Build a hand that moves like yours

These stem toys for kids put a working mechanical hand in the hands of builders ages 8 to 14. Following the step-by-step manual, they assemble the wooden parts into a machine that grips and moves, and discover the science behind it as they go. It is 100% screen-free, confidence-building play that feels like being a superhero engineer. Made from high-quality engineered wood, the finished model is sturdy enough to play with for a long time, and every part needed is in the box, with replacement parts available for life.

Why you'll love it

  • Real mechanics: Build a hand that actually grips, then learn why it works
  • Engineered wood: Durable, safe, good-looking pieces that last
  • Step-by-step manual: Easy instructions make the build smooth and satisfying
  • Everything included: All parts in the box plus lifetime replacement parts
  • Award winning: Recognized by STEM organizations and toy-of-the-year juries

Perfect for: rainy weekends, science fair prep, birthday gifts, Christmas presents
