When I saw that instant freeze...thingy in an old, 1993 movie, Demolition Man, I thought it was a big bogus. How can something so small freeze the whole room, including the bad guy, a living person? Well, although it is bit stretched, freezing water at an instant is ... apparently possible?!
If you could tell me how this is done, let me know please.
UPDATE: I guess this is pretty popular now; to cool pure water (water with low amount of impurities) to below its freezing point, then giving it a disturbance to start the freezing process. There are several YouTube videos that explore this very interesting characteristics of water...
