We all know that “in space, no one can hear you scream,” but what we don’t know—or what hasn’t been all that accurately depicted on film—is how someone would actually die were they just to float off into space. We caught up with Adam Savage at a recent Brain Candy Live! show to investigate just that. While the former Mythbuster says some movies have done a decent job of depicting what could happen if you were just jettisoned into deep space, others have gone totally wrong. The realities, he suggests, are far creepier than most movies have even thought to show. Boiling eyeballs, anyone?
