In an experiment plastic bottles of supercooled water were agitated causing visible amounts of ice to form (the water/ice mixture was filtered into a measuring cup, not a large fraction of ice formed). Why did the agitation ("not a lot needed") set off ice formation?
Is it the large scale water stillness that prevents ice formation?
Is there some kind of "barrier" here that must be overcome?
After the ice forms can we say anything about the temperature of the water?
If we knew the temperature of the water, say 1 degree C below freezing, should we be able to calculate the amount of ice formed after we agitate the water?
Does the amount of agitation needed to cause ice formation depend on the temperature of the water below freezing?
Thanks for any thoughts!
