I'd like to suggest to anyone that thinks that a gram of copper falling a quarter mile and hitting you on the head only "might hurt a little bit," that you definitely go try it and tell us just how "little" it hurts. Before you try this, however, take off your shoe, and drop a quarter on your toe from shoulder height.

What's the terminal velocity on a penny, anyway? It's probably going about as fast as it's going to go after about four stories.
