When something reaches freezing temperature, the molecules start to slow down and come together. It's like they're all having a big party, and they're all clustering together to get cozy! As they get closer, they start to form a crystal lattice structure, which is just a fancy way of saying "they turn into a solid".
But here's the thing: not everything freezes at the same temperature. Some things, like alcohol, have a lower freezing point than water. That's why you can put vodka in the freezer and it won't turn into a solid (although, let's be real, it's still pretty chilly!).
And then there are things like supercooling, where a liquid can drop below its freezing point without actually freezing. It's like the liquid is saying, "Oh no, I'm not going to freeze! I'm going to stay liquid, no matter what!" (Spoiler alert: it eventually does freeze, but it's still pretty cool).
