I'm a big support of supporting everything with science but screw science now. Not everything can be explained with a scientific phrase. I live in canada and after coming home from a long cold day i like to put my hands under some hot tap water because it so quickly makes it warm whereas when I put it under cold water, nothing really happens because my hands are already cold but slowly it will get colder like that. This in my opinion is the exact same thing as hot water freezing faster than cold, because its a bigger transition therefore somehow it changes faster. Where little changes occur slower. You can counter me and say we have nerves and so it makes no sense since water doesn't have nerves but a part of me thinks that water has some kind of nerve like things that allow the same thing to happen.
