What remains less known, however, is whether the charismatic, endlessly curious persona that shines through millions of glowing screens matches the reality of the man when the cameras stop rolling. A recent interview with Scary Mommy provided a firsthand look behind the scenes, offering reassurance to parents everywhere: Mark Rober is precisely the person children think he is.
Speaking via Zoom, Rober discussed his transition from designing hardware for space exploration to commanding a massive digital audience, his philosophy on children’s education, and the launch of his new physical toy line. He also reflected on the surreal experience of achieving "God tier" status among young fans, including the interviewer’s seven-year-old daughter.
The occasion for the conversation was the rollout of CrunchLabs, a new line of hands-on STEM toys currently available on store shelves and online. The collection features products like the Hover Ring Blaster, the Crunchinator, and the Elephant Toothpaste Blast kit. Each product is paired with an exclusive video hosted by Rober, which breaks down the fundamental engineering principles behind the physical toy, ensuring that play and education go hand in hand.
A core pillar of Rober’s entire philosophy is a refusal to dumb down complex concepts for young audiences. Rather than hiding the mechanics behind the toys to let children play mindlessly, his goal is to provide a genuine, transparent look inside how things work.
"We never talk down to kids," Rober told Scary Mommy. "We kind of try and make it so we can smooth that transition into sort of those teenage and then adult years even, like we try to make content that is like a Pixar movie; it just works for all ages."
That instinct traces straight back to his professional roots at NASA, where he spent nearly a decade working as a mechanical engineer on projects including the Curiosity rover. When asked if any skills cultivated during his time in the aerospace sector proved useful for building consumer toys, his answer served as a masterclass in first-principles thinking. The approach relies on breaking any massive, intimidating problem down into small, manageable steps, rendering the individual components entirely approachable.
"That’s very similar whether you’re putting rovers on Mars or you’re putting can crushers in [my daughter’s] kitchen," he noted.
For any parent of a naturally curious child, watching that initial spark of wonder potentially dim as the child grows older can be a source of low-grade dread. When Rober was asked directly if he had practical advice for keeping that inquisitiveness alive into the tween and teen years, his answer avoided vague inspirational quotes in favor of actionable guidance. He emphasized the importance of capitalizing on curiosity while it naturally exists, building enough momentum to carry young people through the more challenging later years.
"To the degree that you can keep them off social media, I think that helps," Rober said. "But I think a bigger thing is you just have to create enough positive experiences in the age where they are naturally curious."
Ultimately, Rober wants children walking away from his content and products with a specific mindset, able to articulate that they like science, building, and being curious, while understanding that failure is not a setback but an inherent part of the process.
The interview took an unexpected turn when the interviewer’s seven-year-old daughter—an aspiring CrunchLabs engineer—entered the home office and crashed the Zoom call. Rober did not miss a beat, seamlessly shifting gears to engage with his young fan in a completely natural, delightful manner.
The pair launched into their own conversation, discussing the mechanics of the Elephant Toothpaste Blast kit. Rober revealed that when he was originally dreaming up the concept, he specifically had parents in mind. The original scientific formula for the chemical reaction would have produced bright red foam, raising immediate concerns about permanent household damage.
"In fact, if you had a two-story house, it’d hit the ceiling in the second story," Rober explained.
To prevent domestic disasters, his team reformulated the chemical reaction so that the resulting foam emerged purely white, ensuring it would not ruin anyone’s home or furnishings. "That’s me looking out for the moms out there," he said with a laugh.
The young fan also seized the opportunity to ask about his favorite video project, prompting Rober to light up as he discussed his famous squirrel obstacle course series. He described the production process of waking up at 6:00 a.m. with a long camera lens, operating essentially like a wildlife photographer determined to outsmart recurring backyard visitors like Phat Gus, Frank, and Marty.
Following a quick photo opportunity, the conversation shifted back to Rober’s own upbringing, prompting the question of what he was like as a child and what he would tell his younger self today.
"I remember my childhood very well," he said. "Which makes it really easy for me to tap into what [kids] would think is really cool. Because honestly, it’s sort of what I think is really cool, right?"
He shared anecdotes about still being the kind of person who cannot resist playing juvenile practical jokes, such as tapping a stranger on the far shoulder and walking around the other side just to elicit a laugh. "That’s not a funny prank. That’s not cool. But I cannot help it."
Maintaining that innate, childlike sense of wonder while simultaneously managing a thriving modern business serves as the fundamental engine behind CrunchLabs. For Rober, preserving that perspective is not just a business strategy; it is also good parenting advice.
