    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!

    Great Projects ALL Year Round!

    First, I want to say how much fun my daughter has putting together the build boxes from CruncLlabs.

    As we get to the end of the school year, she stores them up to do more of them over the Summer when she has more down time. Our dining room table is typically filled with the completed builds for most of the Summer.

    My only issue, if I have one, is the packaging.

    I am not optimistic enough to believe that we'll ever win a "golden ticket" to go to the CrunchLabs HQ. However, we have never once received a delivery that wasn't already opened. This month's was completely removed! To this date, no parts have gone missing. But it seems, in transit, someone is trying to find that "golden ticket" invite.

    Though the physical invitation must be pretty damn cool, I'd rather them just randomly email a winner once a month. At the least, I hope Mark Rober asks the winners what they do for a living. If they have a wildly disproportion number of postal workers winning a trip to CrunchLabs, they might wanna look into it.

    If you have a young engineer in the making or even just a kid who is into tinkering, THIS is definitely for you!

    Grandson LOVES getting his Crunch Labs Boxes

    Grandson looks forward to receiving his Crunch Labs box and now that they are coming every week in the summer, even more excited as noted in the attached video.
