An icicle is a spike of ice formed when water falling from an object freezes. == Formation and dynamics == Icicles can form during bright, sunny, but subfreezing weather, when ice or snow melted by sunlight or some other heat source (such as a poorly insulated building), refreezes as it drips off under exposed conditions.
