Mark Rober uses engineering projects to turn a question into a visual story. A former NASA engineer, he makes science-led videos in which a build, experiment or apparently playful problem becomes a way to explain how things work. The presentation pairs workshop processes with the anticipation of a test, allowing viewers to follow both the idea and the result. His public projects have included elaborate squirrel mazes, inventive devices and carefully constructed pranks. These subjects provide a familiar point of entry before introducing principles of design, physics and problem solving. The emphasis on making and testing gives the films a practical character: the mechanism behind a surprising outcome is part of the entertainment, rather than a detail left off screen. Rober also founded CrunchLabs, which develops buildable projects and accompanying educational videos. Its engineering kits and robotics activities extend the same approach into hands-on learning for children, teenagers and adults. Across his videos and educational work, curiosity is treated as something to act on, through assembling, experimenting and reconsidering a design. His official channels suit viewers who enjoy accessible science with an evident connection to the workshop.
