A Laboratory for Hands-on STEM Projects

We make science and engineering seriously fun.

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.

These boxes every month exceed my expectations. I have two boys and the each have a subscription and look foward to every month and as soon as they recieve it they sit down and put it together no matter hown long it may take. My youngest son gets the Tinker create and at the beginning I was needing to walk him through step by step but now he can assemble it independently. Cannot say enough about this product. Best Christmas gift and money spent

My daughter is 10 and we have tried different boxes: Little Passports, Steve Spangler and she was bored after a couple and wasn't excited each month. But now she gets a Tinker box and can't wait to open it. Then she constantly asks as soon as the month starts when is her next box coming!

The boxes are like a birthday gift every month. Now that my granddaughter has put a few together with her dad, she is now able to follow the directions and do them by her self.

My son loves his kiwi crates. It starts with him receiving a package once a month and the challenge of creating the activity.
