Netflix launched 'Camp CrunchLabs,' featuring Mark Rober's hands-on experiments, special guests, and at-home Super Challenges — expanding his growing library on the platform.
Class CrunchLabs is a free, standards-aligned curriculum for Grades 3–8, developed with the National Science Teaching Association, with 1,000+ videos rolling out for back-to-school 2026.
The flagship CrunchLabs compilation series returned for a fourth season on Netflix, continuing the platform's rapid build-out of a dedicated Mark Rober content library.
The partnership will produce handbooks, activity books, and Klutz Press STEM Lab titles — with two debut titles ('Lava vs. Laser' and 'Extreme Engineering') and a presence in Scholastic's new Discovery Fair.
The monthly STEM subscription box took home the award, with Mark Rober noting the recognition validates that education and entertainment can be a "perfect partnership."

CrunchLabs is the STEM education brand and YouTube channel built around Mark Rober, a former NASA Jet Propulsion Laboratory engineer who developed a large science-entertainment following before channeling that audience into a direct-to-consumer subscription product. The channel functions simultaneously as a content hub and a marketing vehicle for CrunchLabs' monthly Build Box kits — hands-on engineering sets designed for kids, teens, and curious adults. Content is built around accessible science spectacle: physics pranks decoded, levitation and optical illusions explained through engineering principles, and competitive challenges that pit human ingenuity against the natural world. The format deliberately blurs entertainment and education, a lane Rober established well before CrunchLabs launched.
The audience skews heavily male and clusters in the 25–44 age band, pointing to a meaningful parent-and-buyer cohort alongside younger STEM enthusiasts — a high-intent demographic for a subscription product that requires household purchasing decisions. Geographic reach is concentrated in English-speaking markets, with the US driving the overwhelming majority of viewership, followed by the UK and Canada. Consistent upload frequency and steady growth across YouTube and Instagram suggest the brand is establishing reach that extends beyond Rober's personal channel, which gives CrunchLabs a durable platform for education-adjacent and family-focused brand partnerships as it continues to build its own audience identity.
Crunchlabs reaches an audience concentrated in United States primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories, TikTok branded content. As an education creator they map naturally to brands targeting that space. Demonstrated partners include CrunchLabs. Engagement on YouTube runs around 1.4%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of long-form YouTube integrations and Instagram Reels and Stories lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows education content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For United States-focused brands in education and related categories, Crunchlabs offers a defined, creative-fit audience rather than broad, low-intent impressions.

Yes, CrunchLabs was created by Mark Rober, the science entertainer and former NASA engineer who built one of YouTube's largest science channels. Rober founded CrunchLabs to extend that educational energy into a hands-on subscription product, giving subscribers the chance to build real engineering projects at home.
Mark Rober spent roughly nine years as a mechanical engineer at NASA's Jet Propulsion Laboratory, where he contributed to projects including the Mars Curiosity rover mission. That real engineering background is a cornerstone of the CrunchLabs brand — it's what separates the product from generic craft kits and gives it credibility with parents and educators.
CrunchLabs markets its subscription box to kids, teens, and adults, making it one of the few STEM kit brands without a strict age ceiling. The builds are rooted in real engineering concepts, so younger children will often work best alongside a parent or older sibling, which is part of the intended co-building experience.
Camp CrunchLabs is an online STEM program and community challenge initiative run by CrunchLabs, promoted across their channels with the #CampCrunchLabsContest hashtag. It's designed to engage participants through structured engineering challenges in a camp-style competitive format, keeping learners active between box deliveries.
CrunchLabs explicitly targets adults alongside kids and teens — the premise is that hands-on building is rewarding at any age, and tinkerers or engineering enthusiasts are a genuine part of the intended audience. The channel's viewership reflects this, with a significant portion of the audience in their 30s, 40s, and older.
Yes — using illusions and pranks as an entry point for science is a signature part of the CrunchLabs YouTube style. Videos like Magic Refilling Can Prank EXPLAINED and Magic Ring Prank EXPOSED lead with the entertainment hook of a surprising effect and then reveal the real physics or engineering underneath it.
Animals vs Engineers is a recurring CrunchLabs series that pits engineering solutions against the capabilities of the natural world, using animal behavior or biology as the benchmark for design challenges. It fits the channel's broader approach of framing science as a high-stakes competition or adventure rather than a conventional lesson.
Yes, CrunchLabs has been involved with Maker Faire, the flagship event for engineers, inventors, and hands-on creators. It's a natural alignment for the brand, which is built entirely around the idea that building and making things is both educational and genuinely fun.
CrunchLabs actively creates content tied to STEM awareness moments like Fibonacci Day (November 23rd), using those cultural hooks to make mathematical and scientific concepts feel timely and shareable. Anchoring educational content to specific calendar events is a deliberate part of the channel's strategy to keep science feeling relevant rather than academic.
CrunchLabs is based in the United States, and the overwhelming majority of its audience is also American. The channel does draw meaningful international viewers — particularly from the UK, Canada, and India — but the US remains by far its largest and most concentrated market.
