Mark Rober

The Engineering Genius Behind the Camera

Mark Rober has established himself as one of the most influential science and engineering content creators on YouTube. With over 67 million subscribers as of May 2025, Rober has built an empire of educational entertainment through his monthly videos showcasing elaborate engineering projects, scientific experiments, and creative problem-solving.^[1]^[13]

From NASA to YouTube Stardom

Before becoming a YouTube sensation, Rober spent nine years as an engineer at NASA's Jet Propulsion Laboratory (JPL), where he worked for seven years on the Curiosity rover mission to Mars. His contributions included designing and delivering hardware for several JPL missions, including AMT, GRAIL, SMAP, and Mars Science Laboratory. During his time at NASA, he also developed "JPL Wired," a comprehensive knowledge capture wiki system.^[1]^[5]

After leaving NASA, Rober joined Apple Inc. for four years as a product designer in their Special Projects Group, where he authored patents related to virtual reality in self-driving cars. This combination of prestigious technical experience laid the groundwork for his future success as a science communicator.^[13]

YouTube Journey and Content Strategy

Rober's YouTube career began in October 2011 with a Halloween costume video featuring two iPads creating the illusion of seeing through his torso. The video went viral overnight, garnering 1.5 million views in just one day. This early success inspired him to launch a regular channel focused on science, engineering, and DIY projects.^[2]^[3]

Unlike many content creators who post daily videos, Rober adopted a unique strategy of posting only once per month, focusing on high-quality, meticulously produced content. This approach has proven remarkably successful, allowing him to amass over 11.7 billion views across his channel despite having fewer than 150 videos in total.^[14]^[4]

Viral Engineering Projects

Rober is perhaps best known for his series of "Glitter Bomb" videos targeting package thieves. The original video, posted in December 2018, received 25 million views in a single day and has since become an annual tradition with increasingly sophisticated iterations. In later versions, he collaborated with cybersecurity YouTubers and law enforcement to track and arrest scammers, turning entertainment into real-world justice.^[13]

Other viral projects include the "Backyard Squirrel Maze," a series showing increasingly complex obstacle courses for squirrels that has garnered over 219 million combined views across three videos. Rober has also created the world's largest Super Soaker, which broke the Guinness World Record for the largest functional water gun, and numerous other oversized or enhanced versions of everyday objects.^[13]^[5]

Educational Impact and Philosophy

Rober's approach to education is embodied in what he calls "The Super Mario Effect," a concept he presented in a popular TED talk. The principle suggests that learning is more effective when framed as a fun challenge rather than a task with penalties for failure. In an experiment with 50,000 of his followers, he demonstrated that removing the fear of failure significantly increased success rates in learning new skills.^[14]^[6]

This philosophy underlies much of his content, which aims to make science and engineering accessible and exciting to audiences of all ages. His videos often break down complex scientific principles through entertaining demonstrations and experiments.^[13]

Philanthropy and Environmental Activism

Beyond entertainment, Rober has leveraged his platform for significant environmental causes. In October 2019, he partnered with fellow YouTube star MrBeast to launch #TeamTrees, a campaign that raised over $23 million to plant 23 million trees worldwide. The initiative mobilized content creators globally and demonstrated the potential for social media to drive environmental action.^[7]^[13]

Building on this success, in 2021 the duo launched #TeamSeas, aiming to raise $30 million to remove 30 million pounds of plastic and trash from oceans, rivers, and beaches. The campaign exceeded its goal, raising over $34 million and again showcasing the power of creator-led fundraising efforts.^[8]^[13]

CrunchLabs: Expanding Educational Reach

In 2022, Rober founded CrunchLabs, an educational technology company focused on STEM learning. The company offers subscription boxes containing hands-on building projects and engineering challenges for children, along with instructional videos that teach kids to "Think Like an Engineer." This venture represents Rober's commitment to inspiring the next generation of scientists and engineers.^[9]^[13]^[10]

CrunchLabs has grown significantly, with Rober describing it as a "Willy Wonka Factory for engineering" complete with go-karts and Nerf guns. The company offers monthly STEM subscription boxes for children, teens, and adults, combining physical learning materials with Rober's engaging teaching style.^[10]

Audience and Reach

As of May 2025, Rober's YouTube channel ranks #17 worldwide among YouTube influencers with nearly 68 million subscribers. His content consistently generates millions of views, with an average of 9.3 million views per month. The channel primarily appeals to those interested in Science & Technology, ranking #1 in this category.^[12]^[11]

His content's appeal spans multiple platforms, with 3.3 million followers on TikTok and 1.7 million on Instagram. This cross-platform presence allows him to reach diverse audiences and extend his educational impact beyond YouTube.^[12]

Media Appearances and Recognition

Rober has extended his influence beyond YouTube through numerous media appearances, including multiple spots on Jimmy Kimmel Live! (even guest-hosting the show in July 2022), and features on CBS News, CNN, The Tonight Show, Fox, Yahoo! News, Discovery Channel, The Today Show, and Good Morning America. In 2020, he starred in a Discovery Channel hidden-camera show called "Revengineers" alongside Jimmy Kimmel, as well as his own series "This is Mark Rober."^[13]

His work has been widely recognized for bridging entertainment and education, making complex scientific and engineering concepts accessible to mainstream audiences while inspiring curiosity and creativity in viewers of all ages.^[14]
