Icicles form when the air temperature is below freezing, 32º Fahrenheit (0º Celsius). Sunlight or the heat coming from houses melts ice and snow on the roof. The melting water dripping down along the edges refreezes in the cold air, forming a carrot-shaped spike of ice, which we call an icicle. Icicles usually don’t grow very large before breaking by their own weight, but this icicle was about 3-feet long, very big for an icicle.
