You might think freezing is universal, but nope! Alcohol like vodka freezes around -16°F, meaning your freezer at 0°F keeps it liquid. That’s why a bottle of whiskey won’t turn into an ice cube (unless you’re camping in Antarctica).
Even blood doesn’t freeze at 32°F—it has salts and proteins that push its freezing point to about 31°F. So, vampires can breathe a sigh of relief: your veins aren’t icicles in a cold snap.
The weirdest one? Gallium, a metal that melts in your hand at around 86°F. Its freezing point is room temperature, so you can literally watch it turn from liquid to solid just by touching it. Try doing that with an ice cube!
But What IS Freezing, Really?
At its heart, freezing is a phase change: from liquid to solid. Molecules lose energy, stop bouncing, and settle into a rigid structure. It’s like a busy city street at rush hour versus a silent snow-covered field at midnight.

Here’s the cool part: freezing releases latent heat. Ever notice how a bag of ice feels colder than a frozen steak? That’s because the ice is still melting, absorbing heat from your hands. But when water freezes, it gives off energy—so it’s actually exothermic!
Wait, what? Freezing releases heat? Yep, it’s counterintuitive, but think of it this way: when water molecules lock into ice, they throw a little leftover energy into the air. That’s why your car feels slightly warmer when frost forms on the windshield at dawn.
