- The word is derived from Old English īs, which in turn stems from Proto-Germanic *isaz.
- Ice is the only known non-metallic substance to expand when it freezes
- Light reflecting from ice often appears blue due to the properties of Rayleigh scattering, the same reason the sky is blue. Blue light is scattered much more strongly than red in matter which does not absorb visible light, such as ice.
- Until recently, it was widely believed that ice was slippery because the pressure of an object in contact with it caused a thin layer to melt. For example, the blade of an ice skate, exerting pressure on the ice, melted a thin layer, providing lubrication between the ice and the blade.
This explanation is no longer accepted. There is still debate about why ice is slippery. The explanation gaining acceptance is that ice molecules in contact with air cannot properly bond with the molecules of the mass of ice beneath (and thus are free to move like molecules of liquid water). These molecules remain in a semiliquid state, providing lubrication regardless of pressure against the ice exerted by any object - Clathrate hydrates are forms of ice that contain gas molecules trapped within its crystal lattice.
- Pancake ice is a formation of ice generally created in areas with less calm conditions.
- Candle Ice is a form of Rotten Ice that develops in columns perpendicular to the surface of a lake.
- Ice discs are circular formations of ice surrounded by water in a river.
- Ice production is a large business; in 2002, there were 426 commercial ice-making companies in the United States, with a combined value of shipments of $595,487,000.
- Called Romantic Feelings, it is a staggering 115ft high and 656ft long - the largest snow sculpture ever created.

Because I am not loving the weather today...ICE
Yes it is icy out today. In fact, this morning I was so freaked out that I tushie scooted down the front stairs of my home because I didn't want to slip and fall (which I almost did 3 times). It was really scary just walking down the sidewalk and took me forever to get to work. Alas, I did get here (and on time), but I'm very sick of all the ice already and want it to go. I'm more of a mild sunny day type. So here we go... ICE
