- An icicle is the spike-shaped block of ice that forms when dripping water freezes.
- As each cold drip wiggles its way down towards the ground and freezes in the process, icicles are formed.
- Over time continued water runoff will cause the icicle to grow.
- Hanging icicles during winter display the artistry of nature.
- The growth rate in length typically varies with time, and can in ideal conditions be more than 1 cm (0.39 in) per minute
- Some icicles are taller than humans.
- Icicles that hang from an object may fall and cause injury and/or damage to whoever or whatever is below them.
