One controversy that touched Sam Raimi's Spider-Man franchise involved the webslingers. In short, they were a little too biological for some Spider-Man aficionados; there were no actual devices that would have satisfied comic book purists. As we know, Marc Webb's The Amazing Spider-Man is getting back to basics on that count. Mechanical webslingers are the order of the day for Andrew Garfield's Peter Parker, and, as this new viral demonstrates on Evolve Through Engineering shows, they're grounded in real science. Well, movie science at least. Don't try this at home, just to be on the safe side.
