I heard today there is a competition to see who can explain the Mpemba effect (hot water freezes faster than cold).
Physicists still don't understand this too well. Google it for more.
I can't explain it either but I may have found the first practical application. Ice cubes may not freeze overnight and if you drive off the next day what isn't frozen may end up all over your freezer and its contents (I have done the experiment). But using the Mpemba effect you should be able to get the ice frozen before you head off. I haven't yet tried this but the time difference is quite large so it should work.
(sorry I spelled the effect's name correctly in the text but not in the title - but I can't see how to edit the title.)
