Water inside water bottle froze up right after I removed it from the freezer

Question

So here’s what happened, I put water bottles inside my freezer, and looked like it was still liquid inside. But when I removed it, I saw it freezing from top to bottom (not completely frozen, but hardened). What exactly happened?

It’s called “supercooling”. In short, its like a special trick that water can do when it’s really, really cold, and it can stay a liquid even when it’s supposed to be ice!
