We spend 1000+ hours designing & testing every single crate.

What sets our crates apart from typical science kits for kids?

Each of our crates presents kids with a multi-faceted experience that can last for hours, or even days!

Our crates include a magazine with additional science experiments and activities, and lots of rich content to dig deeper into the theme. We also provide online resources and video content for every project, all designed to allow kids to explore further.
