An icicle is a spike of ice formed when water dripping or falling from an object freezes.
Typically, icicles will form when ice or snow is melted by either sunlight or some other heat source (such as a poorly insulated building), and the resulting melted water runs off into an area where the ambient temperature is below the freezing of water (0 degrees), causing the water to refreeze. Over time, continued water runoff will cause the icicle to grow.
The photo above is how the trickle starts on my back roof and the photo below is how the icicles grew after some afternoon melts and evening freezes. See the huge amount of ice actually fills the gutter and then it might back up under the shingles in a fast melt. This is why I always remove the icicles when they are small - I try not give them a chance to build up and possibly back up under the shingles. Some just stay there all winter as I cannot reach them.
Icicles come in various shapes and sizes. Icicles from on surfaces which might have a smooth and straight, or irregular shape; which in turn influences the shape of an icicle. Another influence is melting water, which might flow toward the icicle in a straight line or which might flow from several directions.

Given the right conditions, icicles may also form in caves (known as ice stalactites). They can also form around salty water sinking from sea ice. There can be much damage and injury caused by icicles. Icicles that hang from an object may fall and cause injury and/or damage to whoever or whatever is below them. I can remember Mum always appointing one of us to take the broom out and knock the icicles off the back roof.
(THANK YOU to one of the two VOLUNTEERS that helped take ice off the Library roof yesterday)
Ice deposits can be heavy. If enough icicles form on an object, the weight of the ice can severely damage the structural integrity of the object and may cause the object to break. Whether it be structures, trees, cliffs, poles, wires, caves, etc - BEWARE OF FALLING ICE.

Wow! Those are beautiful. Especially liked the curved upwards ones. Amazing.

I couldn't watch that video over here in Turkey, but I know all about those icicles. Gotta be careful of them. :-)

Goodness me, are any of those on your house now?
It’s very very beautiful but must be quite difficult to cope with too?

Those look like the mother of all icicles! I've never seen anything like that. I guess with the mega snow there , there's lots of water to run off the roof.

This looks very cold brrrr. Although the icicles can be dangerous, they look very nice , like a kind of decoration of the house :) Keep warm.
