The reaction was started at about 80 oC and cooled down by adding ice to the water bath (the extra water was drained from the beaker).  When the water bath got very close to 0 oC the heater was turned on and the water bath warmed up to about 90 oC.  The total elapsed time in this video is about 1 hour.
