So I decided to investigate icicles. As a resident of a state with cold winters, I know icicles form when rain or melting snow drips down on a surface. When droplets slip down an icicle, a small amount of heat is released. This heated air travels upwards and slows down the growth of the icicle's top, while the tip is elongated.
Scientists believe that future studies into the mathematical equations that govern icicle growth -- the same that apply to stalactites -- could help in the prevention of icicle formation on power lines.
