Because next time you eat fries, use de-icer, or stare at a frozen lake, you’ll know why it behaves the way it does. That little chart is a map of how water fights the cold with a little help from salt.
And honestly? It’s just cool (pun intended) that a sprinkle of something so tiny can change the rules of ice. So grab a handful of salt, a thermometer, and a freezer—go make some slush and feel like a curious scientist. Who knew chemistry could be this refreshing?
