The term 'Frozen Water Drops' can be summed up in one word: icicle. An icicle is a spike of ice that forms when water droplets freeze and hang from the edge of an object, such as a roof or tree branch. Icicles are usually formed during cold weather when temperatures drop below freezing. They can also form when water droplets come into contact with a cold surface, such as a metal pipe. Icicles can range in size from a few inches to several feet long.
