Mark Rober

Rober was raised in Brea, California, the youngest of three siblings. He graduated from Brea Olinda High School in 1998. He became interested in engineering at a young age, making a pair of goggles that helped avoid eye irritation while cutting onions. Rober graduated from Brigham Young University (BYU) in 2004 with a Bachelor of Science in mechanical engineering. He later earned a Master of Science in mechanical engineering from the University of Southern California (USC) in 2014.

Early career

Rober joined NASA's Jet Propulsion Laboratory (JPL) in 2004. He worked there for nine years, seven of which were spent working on the Curiosity rover, which is now on Mars. He designed and delivered hardware on several JPL missions, including Advanced Modeling Technology (AMT), GRAIL, SMAP, and Mars Science Laboratory. While at NASA, Rober was one of the primary architects for "JPL Wired", which was a comprehensive knowledge capture wiki. He published a case study about applying wiki technology in a high-tech organization to develop an "Intrapedia" for the capture of corporate knowledge.

Science communication

While at NASA, Rober began making viral videos. His videos cover a wide variety of topics, sparking ideas for April Fools' Day pranks and teaching about beating an escape room and filming primates in zoos non-invasively. He also advocates for science in many of his videos.

In October 2011, Rober recorded his first YouTube video. It shows a Halloween costume that used two iPads to create the illusion of seeing through his body. His video of the "gaping hole in torso" costume went viral, receiving 1.5 million views in one day. The following year, Rober launched Digital Dudz, an online Halloween costume company that specializes in Halloween costumes based on the same concept as the video (to which Rober holds the patent). The company took in $250,000 in revenue in its first three weeks of operations, and by 2013 his app-integrated costumes were sold in retail stores such as Party City. The costumes were widely featured on news channels such as CBS News, CNN, The Tonight Show with Jay Leno, Fox, Yahoo! News, the Discovery Channel, The Today Show and GMA. He sold the company to UK-based costume company Morphsuits in 2013.

In December 2018, Rober posted a video showing how he tricked parcel thieves with an engineered contraption that sprayed glitter on the thieves, emitted a foul odor via fart spray, and captured video of the thieves. The video went viral, receiving 25 million views in one day. Rober later removed two of the five incidents caught on tape after discovering that two of the thieves were actually friends of a person he hired to help catch the package thieves. Rober posted a follow-up in December 2019, teaming up with Macaulay Culkin and featuring an improved design. Rober would post another follow up a year later with a third edition of the bomb. While designing it, Rober collaborated with Jim Browning, Scammer Payback, and various state and federal authorities to use the glitter-bomb bait package as a tactic to track and arrest money mules and their supervisors, who were working with scamming call centers in India to rob elderly people of thousands of dollars. This was in conjunction with a multi-YouTuber movement to get back at and shut down scam callers, while raising awareness to prevent other people from being scammed. The videos resulted in the shutdown of these call centers and the arrest of 15 senior officials involved in the scams.

In 2020, Rober released the video Backyard Squirrel Maze, showing a backyard obstacle course he built to deter squirrels from stealing food from his bird feeders. He released a follow-up video of an updated obstacle course a year later. By September 2023, the original video had 114 million views; the second video, 80 million and the third, 25 million.

Rober has contributed articles to Men's Health, and gave a TEDx presentation in 2015 How to Come Up with Good Ideas and another one entitled The Super Mario Effect – Tricking Your Brain into Learning More. He has also made numerous appearances on Jimmy Kimmel Live!, including guest-hosting the show in July 2022.

In 2018, it was reported that Rober had been secretly working on virtual reality projects for Apple, including the company's on-board entertainment for self-driving cars, for which Rober wrote two virtual reality-related patents. Rober worked as a product designer in Apple's Special Projects Group from 2015 to early 2020. In 2020, Rober starred in a Discovery Channel hidden-camera show Revengineers alongside Jimmy Kimmel. He also starred in the series This is Mark Rober on Discovery. Rober is also the host of a Netflix competition which began in 2026. The show is produced by Jimmy Kimmel and CrunchLabs.

Rober moved to Sunnyvale, California, in 2015. Rober is an advocate for autism awareness, as his son has autism. In April 2021, Rober and Jimmy Kimmel hosted a live stream, raising $3 million in support of NEXT for AUTISM.

Rober was previously married, until his divorce in 2021.

In October 2019, MrBeast and Rober released a project labeled #TeamTrees, after a tweet that suggested that MrBeast should plant 20 million trees. MrBeast and Rober worked with YouTubers across the globe in an effort to make this come true. The goal was to raise $20,000,000 for the Arbor Day Foundation by 2020, while the Arbor Day Foundation would plant one tree for each dollar raised.

On October 29, 2021, Rober and Donaldson created #TeamSeas, another fundraiser which had a goal of $30 million. The money went to The Ocean Cleanup and the Ocean Conservancy, two not-for-profit organizations. They planned to use this money to remove 30 million pounds of debris and trash from the ocean.

Rober and MrBeast launched Team Water in 2025. The project is a collaborative fundraiser that is a follow-up to the Team Trees and Team Seas campaigns. By August 2025, over $40 million was raised for WaterAid.

Rober created an educational initiative called Class CrunchLabs which provides $60 million of free STEM educational lessons, experiments, and teach training at no cost to schools. He announced the initiative during a TED talk in 2026.
