Pennies dropped from skyscrapers won't kill you.

Strangely, I'm disappointed by this news. Some myths should never be busted. From ABC News:
Many visitors outside of the famous skyscraper we spoke to had heard all about killer pennies. "Anybody who gets hit by that penny is about to die, 'cause that's a long way for a penny to fall," said one young man. "It could actually go through someone's skull," said another.

[...] We thought so too, so we asked University of Virginia physics professor Louis Bloomfield about it. "They're thinking of a world without air ... but air resistance is a big deal for little things. It slows down leaves, it slows down raindrops and it slows down pennies," he said.

"The penny is heavier [than a raindrop] but it flutters as it comes down. It's very unstable in the air."

Bloomfield has heard about the myth so often he tackles it in his latest book, "How Everything Works."

"Pennies, they're not aerodynamically stable ... they catch a lot of wind ... basically they're safe," he said.
