Here's a scientific mystery for you: does hot water freeze faster than cold water?
The answer is: we don't know.
You're probably thinking: how can we not know?
I mean, we've all got water.
Most of us have a freezer.
This seems like a pretty simple experiment.
Well, you're right, it is… it also isn't.
The experiment has been performed, by brilliant people all over the world.
And in those experiments, SOMETIMES hot water freezes faster than cold water.
And sometimes it doesn't.
