Is it really true that a person walking on the street would be killed if he were to be hit on the head by a penny dropped from the top of The Empire State Building?
See http://en.wikipedia.org/wiki/MythBusters_(season_1 )#Episode_4_.E2.80.93_.22Penny _Drop.2C_Microwave_Madness.2C_ Radio_Tooth_Fillings.22 “A penny dropped from a skyscraper lands with enough force to either kill a pedestrian on the sidewalk below or embed itself into the sidewalk. (Busted) A penny’s terminal velocity is too low and its mass too small for it to penetrate human skin – let alone penetrate concrete or asphalt. Even when fired from a rifle, the penny was unable to penetrate concrete. It did, however, decimate the ballistics gel dummy.
