the diagram that @morbo shows is a interesting one.
Did you notis that the tempatre of the 2 water samples stays the same for a longer time period?
it's about 5000 seconds
it's like the water is freezing at 4 degrees <img src="/ubbthreads/images/graemlins/eek.gif" alt="" />
interesting to know also that that about 4 degress celcius water has the highest density
