Extruding Ice from Steel Fences and Pipes with Diurnal Freeze/Thaw (2008) (my.ilstu.edu)

Pretty cool. I don't ever remember seeing this occur anywhere. More examples of this occurring in nature on his main page: http://my.ilstu.edu/~jrcarter/ice/diurnal/

3D printing for water(ice)?

Wondering if you could make winter ice fountain sculptures out of this phenomenon

anybody have a line on time-lapse video of this phenomenon?

I wonder what would happen if you threw some motion on the pole. Make it spin around and see what patterns you get

Somewhat related is needle ice[1] and ice wool. Temp and humidity differences cause curious ice formations.

Reminds me of "ice jacking" that was blamed when a ski lift collapsed in Whistler.

Exotic beautiful cold desserts, anyone?

To me this seems straightforward.

The expanding ice forces water to flow slowly out any region it can due to hydraulic pressure (no mystery here).

At cold temperatures the water flowing through a crack freezes, taking the shape of the hole it came out(again, no mystery here).

While it's beautiful, I'm not sure how this is news.

Something similar happens in the New Jersey area around the forests (and I imagine other foresty places with cold weather) if you're hiking and you look down during some frosty days you can see ice being extruded from the ground in a way that looks like ice spaghetti. It was pretty neat the first time I saw it.

Eerily reminiscent of tin whisker formation.

This would be a delicious form of ice cream

A time lapse would be awesome!

This is reminiscent of these plants: http://www.greatstems.com/2013/12/beautiful-ice-sculptures-o...

Would be fun to try this with Bismuth.
