    My son runs to the mailbox!

    Every month, my son will go down our very long driveway to get the mail so he can get his crunch labs box and get started on the build. He’s 7 years old and we are on his third subscription. I would like them to be just a bit more challenging, as he gets them put together in minutes and asks me daily, when the next one is coming.

    The Best Gift Ever

    My son has been a fan of Mark Rober's for quite some time. He knows lots of facts about things he has done and can rattle off things he has learned. So, when he asked for this box last Christmas, I hopped on it. Every month he gets an amazing build and learns new things. The projects are well made and he loves collecting the gears for his plaque. He even had his spirit rock be a CrunchLabs themed rock this year! This has been worth every penny!

    Can We Check the Mailbox for My CrunchLabs Box?!?

    My son asks almost daily if we can check the mail for his CrunchLabs box. And as a homeschool mom, I love the awesome science information he gets from each video that accompanies the builds! My kiddo can also do the builds on his own with clear steps in the manuals and help from the video when he needs clarification. We’ve had other subscriptions for STEM in the past that gave us some cheap parts that broke after they worked once, but that’s not what we get with CrunchLabs. My kids all play with the launcher and other box builds a lot and make other creations with them too and they hold up. You can also get replacement parts if you lose any…more discs anyone?

    I can’t thank Mark Rober and his awesome team enough for inspiring my little engineer and sharing their love of science with the next generation! So thanks again!! You guys are awesome!
