Mark Rober

Mark Rober is an American YouTuber, engineer, and inventor who makes science and engineering projects entertaining for millions. With over 78 million subscribers on YouTube, he is best known for viral hits like the Glitterbomb series and the Backyard Squirrel Maze. His videos blend clever engineering with playful humor, often featuring elaborate builds that teach STEM concepts without feeling like a lesson. Rober's channel has accumulated more than 17 billion views, making him one of the most-watched educational creators on the platform.

Before YouTube, Rober spent nine years at NASA's Jet Propulsion Laboratory, working on rover arms and descent-stage jet packs for the Curiosity rover. He later joined Apple's Special Projects Group as a product designer. In 2019, he left Apple to focus on YouTube full-time. He co-founded TeamTrees with MrBeast, raising over $20 million to plant 20 million trees. In 2022, he launched CrunchLabs, a subscription service that delivers engineering toys to kids each month. As of 2026, he is developing a new TV series and continues to create content that inspires the next generation of engineers. He has also delivered a TEDx presentation on creativity and learning.

Mark Rober was born on March 11, 1980, in Los Angeles, California, and raised in Brea, California. He is the youngest of three siblings. He was a quiet kid who didn't talk until age 3 or 4, and his family often described him as spacey. In third grade, he scored so high on a standardized test that his mother thought the school had made a mistake. He graduated from Brea Olinda High School in 1998.

Rober earned a BS in mechanical engineering from Brigham Young University in 2004. During his freshman year, he built a contraption using a metal yardstick, duct tape, and fishing line to steal a friend's Nintendo 64 when the friend wasn't home. After college, he landed his dream job at NASA's Jet Propulsion Laboratory, which he calls Disneyland for engineers. He heard about the opening from a professor and submitted his résumé. While at NASA, he earned a master's degree from USC in 2014 and started a NASA-wide wiki to share information, which won him one of the agency's top internal honors. He also displayed an early interest in engineering, once making a pair of goggles to help avoid eye irritation while cutting onions. His first YouTube video, posted in 2011, featured a Halloween costume made of iPads and got 300 views — a number that made him feel on top of the world. [edit]

Rober's breakthrough came in 2018 with the Glitterbomb video, a trap for package thieves that exploded with glitter and fart spray. It went viral, racking up tens of millions of views and spawning sequels. In 2019, he co-founded TeamTrees with MrBeast, a fundraiser that raised over $20 million to plant 20 million trees. That same year, he quit Apple to pursue YouTube full-time, and his channel crossed 10 million subscribers and 1 billion views.

In 2022, he launched CrunchLabs, a monthly subscription box that teaches kids engineering through hands-on projects. The service quickly grew to hundreds of thousands of subscribers. In 2023, he delivered the commencement address at MIT. In 2025, he and MrBeast launched a $40 million fundraiser for clean water. As of 2026, his YouTube channel has 78.4 million subscribers and 17.5 billion views, and a new TV series is in pre-production. He has also appeared multiple times on Jimmy Kimmel Live! and guest-hosted the show in July 2022. In 2021, he was named IET STEM Personality of the Year and received an IET Honorary Fellowship. In 2024, he received the FIRST Robotics Competition Founder's Award for promoting STEM education. [edit]

Rober's on-screen persona is approachable and playful — he often wears a backwards baseball cap and speaks with infectious enthusiasm. His content is known for the carrot approach to learning: making science so fun that viewers absorb knowledge without realizing it. Fans, mostly young STEM enthusiasts, appreciate his blend of humor and technical detail. He frequently collaborates with MrBeast and Vsauce, and his videos are praised for their high production value and clever engineering. Rober describes himself as having "the mind and humor of a 12-year-old." He has been featured in BYU Magazine and various online publications. [edit]

Mark Rober stands as the 51st most famous person in Creators & Influencers, a standing confirmed by the iFANN Global Fame Rankings for August 2026. This placement reflects his sustained dominance across global media coverage and digital consumption signals. While his fanbase lacks a formal moniker like "Swifties" or "Beyhive," the community identifies simply as "Rober fans" or "science enthusiasts." Despite the absence of an official name, this group operates with remarkable organization, flooding social platforms with homemade recreations of his glitter bomb traps and CrunchLabs kits. Their influence extends beyond mere viewership; they actively coordinate to spike video metrics immediately upon release and mobilize for charitable causes aligned with his engineering ethos. A prime example occurred in May 2026 when fans supported a Make-A-Wish collaboration that granted a young leukemia survivor a dream trip to Disneyland alongside Disney and Rober himself. The community also rallied behind his educational initiatives, such as the free "Class Crunchlabs" STEM curriculum announced in June 2026. Their culture thrives on shared appreciation for engineering humor and inside jokes regarding his catchphrases like "friend of science." This loyalty translates into tangible economic impact, driving sales for his ventures and ensuring his announcements regarding partnerships with companies like Rivian generate significant buzz in both automotive and education sectors.[edit]

Before achieving YouTube stardom, Mark Rober sneaked a photo-realistic image of the alien Alf into a picture of the Curiosity rover he helped build at NASA. He also initiated a pumpkin-carving contest at JPL that remains active today. His time at Apple yielded patents related to virtual reality in self-driving cars, and his first viral video featuring iPads eventually led to the creation of Digital Dudz, a company specializing in app-integrated costumes. During his tenure at NASA, he famously meddled with his supervisors' presentations. Despite his high-level engineering success, he admits to possessing the mind and humor of a 12-year-old. Beyond these facts, a cornerstone of his legend is the real-life deployment of GPS-tracked glitter bombs designed to catch package thieves, an operation that resulted in multiple arrests and transformed internet pranks into a legitimate law enforcement tool. Fans still retell the story of how he balanced building these devices while employed at NASA before transitioning to full-time content creation. His cultural mythology was further cemented when he appeared on the Netflix series Schooled, announced for casting in March 2026, bridging traditional education with modern entertainment.[edit]
