Engineering as a series of ambitious practical challenges
Mark Rober's CrunchLabs centres on the former NASA engineer and creator's science playground. The series turns engineering into a succession of physical challenges, combining large builds, everyday materials and experiments designed around a clear outcome. Rober is credited as both creator and on-screen lead.
The projects range from competitive pumpkin carving to an attempt at a giant elephant-toothpaste foam reaction with Science Bob. An episode about magic tricks uses ordinary objects to explain the mechanisms behind apparently impossible effects. These smaller demonstrations sit alongside builds whose scale is itself part of the experiment.
From spectacular builds to useful inventions
Uncovering America's Underwater City uses scanning equipment to investigate a submerged settlement. A Wheelchair Like You've Never Seen starts from a young fan's experience and develops a chair with features including self-balancing wheels. Bed Bugs: The Truth Revealed brings experiments and expert involvement to a familiar household problem.
Other instalments feature elaborate anti-theft glitter packages, a rigged Halloween candy bowl and a tour of Rober's warehouse laboratory. The collection moves between explanation, entertainment and practical design, with individual projects providing the narrative rather than a continuous story that must be watched in order.
