How CrunchLabs Works

Thinking like an engineer means you're resilient. It's getting back up after being knocked down and approaching things differently. That determination helps kids tackle everyday challenges and it's the same determination that puts rovers on other dang planets!

Best gift! He had the box open and was building within moments of receiving it. Then he showed his siblings and his neighborhood friends just how cool it was!

From CrunchLabs boxes to National Invention Convention! I cannot thank Mark Rober enough for fostering a love and passion for building and STEM in my kids.

I just completed Year 1! And I was awarded the Most Passionate Engineer last year in 6th grade. Thanks for making engineering fun.
