Subject: Could you please tell me a little about the phenomenon called supercooling

I a Grad student at the University of Windsor, Ontario, Canada. 
I was recently helping a friend out with first year chemistry 
(she was writing up the conclusions for an experiment regarding 
the determination of the freezing point of a solution) and she 
put forward a question regarding the supercooling phenomenon.  
he asked "why does the organic compound solution cool to below 
the freezing point (when cooled rapidly) without freezing and 
then warm up to the freezing point before actually freezing ?"
I could not find the reply in any of the physical chemistry 
books at the library. Could you please kindly answer the 
question for me ?
