Adam Savage and Jamie Hyneman, two Hollywood special-effects artists, spend each episode putting urban legends to a physical test rather than just discussing them. This entry sends the team underwater and up into the air for a diving-themed double feature, checking whether myths about plunging from great heights or surviving underwater mishaps hold up when built full-scale and tried out. The show's method stays consistent across the series: state the myth, design a rig or experiment that reproduces the conditions, run it with instruments recording the result, and rate the outcome confirmed, plausible, or busted. Savage and Hyneman split into separate builds more often than not, comparing approaches and arguing over methodology on camera. Explosives, custom-built dummies, and pressure gauges show up whenever a myth calls for force or depth rather than clever engineering alone. The appeal is in watching the rig fail or work exactly as predicted, with the raw data from each test standing in for a verdict instead of a narrator's summary.
