icicle

n. hanging tapered mass of ice formed by the freezing of successive water droplets

Icicle (yacht) is also the name of the largest Ice yacht An icicle is a spike of ice formed when water dripping or falling from another object freezes. Typically, icicles will form when ice or snow is melted by either sunlight or some other heat source (such as heat leaking from the interior of a heated building), and the resulting melted water runs off into an area where the ambient temperature is below the freezing point of water (0°C/32°F), causing the water to refreeze. Over time continued water runoff will cause the icicle to grow.
