The video I seen in fire fighter training years ago showed a guy with a Pepsi can of all things. It gives a real good idea of the liquid transferring heat. When the torch moved above the liquid level, catastrophic failure occurred. (it was water BTW). I can't find a link to the video, but will look some more.
