Every month a Build Box arrives with the most awesome build-it-yourself STEM toy kits and an exclusive video from Mark Rober! When shown the toys and videos, 9 out of 10 of our kid testers freaked out – the 10th was too busy playing with the toy to answer our survey!

Each Build Box is centered on a different engineering concept (or superpower), and features a toy that uses that superpower for kids to build, learn, and play with. Each box includes project components for the build-it-yourself toy, a booklet with picture-based instructions, STEM concept explanations, and activities and challenges that take the toy to the next level, and a gear badge that celebrates the engineering superpower they just learned about.

You will receive 1 box per month for as long as you are subscribed! We have DOZENS of toys lined up for years of engineering education and fun.

Not right now. We put a lot of thought into the sequencing of Build Boxes to optimize learning and having an awesome good time. We carefully consider the types of projects and underlying mechanisms that help kids gain engineering superpowers through the Gear Badges. What we’re saying is, trust us, you’re gonna have a blast.

No, each monthly Build Box is its own unique and special snowflake, and we won’t send the same box twice to a subscription. You are able to view the Build Boxes received on your account dashboard. If you have questions or concerns, helpful nerds are standing by at

Plus, we have YEARS of toys lined up for you. It's a journey :)

For now, we only have one line of Build Box subscriptions designed for children ages 8-12+. But we don’t know how to shut off our brains, so we’re always thinking about new ideas. We hope to offer more subscriptions and products in the future, so please visit our website and watch Mark Rober’s monthly videos for updates.

Once your order is placed we hustle to fulfill it in 1 to 3 business days. If you’re in the United States, your Build Box should be in little hands within 4 to 7 business days.

You can click the “unsubscribe” link at the bottom of emails from CrunchLabs. Contact if you need further assistance.

It is our policy not to accept unsolicited submissions of creative material. We hope you understand that it is the intent of this policy to avoid the possibility of future misunderstandings when projects developed by our professional staff might seem to others to be similar to their own creative work.

We love press! Please shoot our team an email at


Actually yeah! It’s a big warehouse in California that we converted into the ultimate design and engineering space. The only warehouse in the whole state, in fact, with a secret entrance through a claw machine. We love our secret lab so much that we want to share it – that’s why we have a Platinum Ticket to let lucky winners come and visit! NO PURCHASE NECESSARY. Ends 5/31/24. 50 U.S. & D.C., 18+. See Official Rules for full details.

Basically, we’re a company full of well educated grownups with child imaginations. We’re always thinking up TONS of toy ideas, and then prototype the ones that are the most exciting. After that, we keep prototyping, and then prototype some more, and then cut the ones that don’t make us giggle till we pee, and then get some helpful kids and lucky adults to play with the ones that do, and then guess what? More prototypes, and then something stops working, so we make more prototypes, and then we think it’s finished, and then somebody goes “what if…” and we all go, that’s way more awesome, so then (you know where this is going)… new prototype, tons of fun, we giggle somebody pees, and it goes on like that. Basically we keep building and testing and rebuilding and retesting until it’s as awesome as it can be. “Think Like an Engineer” is our internal motto too, so only the best of the very best, A+, all-star, home run ideas make into your Build Box subscription.

Build Box Subscription

Ok that’s two questions, but here goes. We design each toy to be a little bit challenging for kids 8-12+, in the same way a good puzzle is challenging. But ours comes with a step-by-step illustrated instruction booklet along with a video of Mark Rober walking kids through each step. We test with 8-12 year olds extensively and prototype for months to make sure each toy is a smooth and enjoyable build. With the help of the video, the instruction booklet, and a dash of tenacity, tons of kids are nailing it and successfully and independently building and playing with Build Box.

CrunchLabs Build Boxes are designed for kids ages 8-12+, but plenty of other kids and adults have enjoyed them too! Build 'em alone or build 'em with friends and family! We know some 30 year olds around here who can’t stop sneak attacking each other with disc launchers. We test every product with third-party testing agencies to ensure the products comply with US and EU safety standards for kids ages 8-years and older. Parents and guardians can gauge the appropriateness for their kids, but we have worked hard to ensure that they’re a blast for the intended age range.

Nope! We think we thought of everything! All the stuff you need to make the toy is included in the Build Box, even batteries. You will need an Internet connection and a kid-safe device to watch the Mark Rober video episode, but you don’t need the video episode to complete the build! In the booklet, we do offer ideas for additional games and challenges that may require other materials – but those are supplemental and not required for the main build and play.

BUT, sometimes in engineering, stuff goes wrong. If on the off chance there are parts missing, go to your account dashboard and visit the webpage for your Build Box. Fill out the form to request missing parts. If you have further questions contact  

It depends! We try to make each build 30 to 60 minutes on average for an 8-12 year old. If your kid likes to take a lot of snack breaks, or there’s a pesky sibling, or they can’t stop laughing because the dog fell off the couch, or they just need to clear their head by running around in circles, they can always come back later to finish.

Currently, we don’t offer an option to purchase individual Build Boxes (though that may come down the road). We have crafted MULTIPLE years of engineering fun and learning, so we think a subscription is the best.

If you want to be the first to hear about what we’ve got in store, join our mailing list (at the bottom of this page)!

To get our Build Box subscription boxes, you’ll need to subscribe. We may offer other subscriptions or stand alone products in the future, but not currently.

We couldn’t do CrunchLabs without Earth, so we believe the best way to inspire responsible engineering is to lead by example:

Our packaging is compostable. We use an uncoated cardboard box and compostable plastic substitutes to package and ship our boxes - Our toys are for kids to play with, not sea turtles to eat.

Our toys grow on trees. We use as much wood as possible in the design of our toys.

Our toys stay out of the landfill longer. We make our toys robust and repairable so they can be enjoyed for as long as possible.

Our Build Boxes are designed for one user, so we recommend a subscription for each kid. Besides, how are you supposed to defend your position in a disc launcher battle with only one disc launcher?

Not necessarily, but the Build Box extras are designed to be, well, extras for specific toys in the CrunchLabs Build Box subscription. That’s not to say you can’t figure out something fun to do with a pack of extra disc launcher disks… think like an engineer! You’ll come up with something!

Of course! We test every product with third-party testing agencies to ensure the products comply with US and EU safety standards for kids ages 8-years and older. The safety standards check for whether the toy is safe and sturdy for its intended play, and that unsafe chemicals don’t make their way into the toy during production.

First of all, you rock for being a teacher, and because you’re inquiring about CrunchLabs Build Boxes, you’re apparently a really cool one, too. To answer your question, yes! We offer a 10% discount on orders of 20-200 build boxes, and a 15% discount on orders larger than 200 build boxes. Whether you want to order for your classroom, after school club, or homeschool cooperative, we can help.

We also offer tax exempt orders if qualified. Please submit proof of your tax exempt status when requesting a quote.

First of all, what a lovely person you are.  How very thoughtful.  Now, to your question… If you live at a different address than the recipient, we’d suggest buying them a gift credit! Since there’s a lot of exclusive content tied to your account, the experience will work best if the account holder for the subscription lives in the same household as the recipient of the subscription.

Learn more here!

This is to purchase a virtual gift credit. This is a great option if you’d like to surprise someone with the joys of science outside of your household. If you’re in the same household as the subscription recipient, and you want to manage the subscription for them, it’s probably best to subscribe directly for them.

The whole experience works best if the person who manages the subscription lives in the same household as the subscription recipient. For the subscription recipient, there’s a lot of exclusive content that’s accessible through the subscription account (including the build videos!). For the account holder, the subscription account is also where they can update or change shipping addresses, pause the subscription, request replacement parts, and give feedback on each box. Basically a big chunk of what makes these so much fun (and educational) are the build videos with Mark and the exclusive content you get when you subscribe!
