sublimation is a solid transitioning into a gas and skipping the liquid phase. Regelation best described is localized point heat generation in a small space.
I discover super-cooled water in my garage this weekend. It was ~4 degrees Fahrenheit, and with a snowstorm on the way it seemed like a good time to clean out my side of the garage so I could fit my car in. As I was collecting up some bottled water I noticed that, while most of the bottles were cloudy from small bubbles in the ice, one was clear because it was still liquid. When I tried to pick it up it instantly went cloudy all the way though as it turned to ice. It ended up a bit slushy, not quite frozen solid. I guess the phase transition gave up enough heat to bring the temperature up to 32 degrees without quite freezing all of it.

I did know that ice skating works because your weight melts the ice it's in contact with.
I'd never seen the string trick.
Crystal Palace is currently in the regelation zone.
Yes, I did know that, and that's why glaciers move also.
And I think sublimation is ice evaporation in a freezer?

Sublimation is Roy Orbison's voice evaporating In Dreams:
Echoes of ranchera music offer bittersweet counterpoint from the lulling intro, through the aching verses to a finish that just seems to evaporate.
"Let us learn something" is such a great start-the-day message. I would have his voice and that sentence as my alarm clock ring.
