Could Jack Sparrow Really Use A Rowboat As A Submarine? | MythBusters

One of the most beloved scenes in Pirates of the Caribbean shows Jack Sparrow and Will Turner casually walking along the ocean floor using an upside-down rowboat as a makeshift submarine — the air pocket inside providing everything they need — and Adam and Jamie, being constitutionally incapable of letting a physics question go unanswered, loaded themselves with 60 pounds of period pirate gear to overcome their own buoyancy, then added 500 pounds of weights to the boat itself, and watched both attempts fail completely as the boat refused to stay submerged under any condition they could engineer, eventually calculating that it would take more than 2,000 pounds of continuous downward force to make the scene work in real life, proving definitively that Jack Sparrow's most charming escape was pure Hollywood magic from start to finish — and that physics, as always, has absolutely no respect for cinematic genius.
