The big idea that brought Tinker Crate to life...

When we were first designing Tinker Crate, one of our advisors — a retired Professor of Science Education at Stanford University — challenged us to think about what STEM really means, beyond just “Science, Technology, Engineering and Math”.

Our response was that STEM is a key to creative problem solving, a foundation for critical thinkers, and a pipeline to innovation. Our mission in creating Tinker Crate is to help kids gain these crucial skills through hands-on activities that are also seriously fun.

The perfect STEM crate for kids ages 9-14

Over 50 million crates of fun... and counting!
