CrunchLabs is an engineering-focused subscription box created by Mark Rober, a former NASA engineer and popular YouTube creator known for making science and engineering genuinely exciting for kids. Each box delivers a hands-on build project, paired with a video from Rober explaining the science and real-world applications behind it, rather than just assembly instructions.
The company offers three subscription tracks by age: Creative Kit (ages 6-10, fostering creativity), Build Box (ages 8-12, hands-on engineering), and Hack Pack (ages 14+, robotics and coding). Families can subscribe monthly or prepay for an annual plan at a lower rate — current pricing is available on their website.
What Families Love
Created by Mark Rober, a former NASA engineer whose genuine enthusiasm makes engineering feel accessible and exciting to kids.
Each build is paired with a video explaining the science/engineering behind it, not just assembly instructions.
Multiple tracks (Creative Kit, Build Box, Hack Pack) span a wide age range, from younger builders through teens learning robotics and coding.
Projects are genuinely well-designed and satisfying to build, not just educational filler.
Things to Consider
Not a full curriculum — best paired with core academics rather than used alone.
Best suited to kids who already enjoy hands-on building; may not land the same way with less mechanically-inclined kids.
Three subscription tracks by age: Creative Kit (ages 6-10), Build Box (ages 8-12), and Hack Pack (ages 14+, robotics/coding).
