Now, let's get a little sciency for a second (don't worry, it won't hurt, I promise!). The freezing point of water is the temperature at which the liquid turns into a solid. It's like a little party in the molecules, where they all slow down and start sticking together, forming ice crystals - it's pretty awesome!
But, here's a fun fact: the freezing point of water can actually vary depending on things like pressure and impurities in the water. Like, if you're at a really high altitude, the freezing point of water can be lower than 0 degrees Celsius - mind blown, right?
