Learn more about Tinker Crate from KiwiCo

We believe that STEM is a key to creative problem solving, a foundation for critical thinkers, and a pipeline to innovation. The design of Tinker Crate reflects this. We're not just another science kit. We create "low threshold, high ceiling" projects, so they're accessible and fun for all types of learners.

Our goal kids to build their problem solving skills and to gain the CONFIDENCE and CURIOSITY to tackle problems where there's no one right answer. We can’t wait to see all of the light bulb “AHA” moments of discovery and understanding.
