A side note from the Russian -Finnish war
From the writer Malaparte comes the tale of the tragic death of a thousand horses in the icy waters of Lake Ladoga in Russia during the winter of 1942. In trying to escape a forest fire caused by aerial bombardments, a hoard of horses jumped into the lake. Despite a recent cold snap, the lake was not frozen solid. As the horses desperately swam toward the other shore, their heads held above the water, a loud noise could be heard: the water suddenly froze, encasing the animals in ice.
The next morning, the sun shone down upon the rigid manes, covered in transparent icicles. Immobilized, each head was a sculpture that in other circumstances would have been a thing of beauty.
Supercooling: When cooled very rapidly, pure water can reach temperatures below its freezing point without solidifying for quite a long time. But toss a few grains of sand into it, and the water will freeze instantaneously. Likewise, water that is heated very quickly will not necessarily come to a boil when it reaches 100 degrees Celsius. This state is very unstable.
