The authors of The Science of James Bond note that the movie Goldfinger has spawned two enduring urban legends: 1) That if you shoot out the window of a plane flying at 35,000 feet, the resulting depressurization will create enough force to suck a person through the hole. Not true! The authors say the airflow wouldn't even be enough to lift a person.
2) It is possible to suffocate by completely covering yourself in gold paint. Therefore, professional dancers who paint themselves know to leave a small bare patch of skin for air. Again, total myth. The authors state that the only danger of being covered with gold paint is "pores being clogged by the paint, causing overheating."
