It’s that time of year again—kids are glued to the TV, fingers crossed for a snow day, while parents rush to the store, clearing out the bread and milk like it’s the apocalypse. But in the midst of all this winter chaos, you’ve probably noticed those big trucks out on the roads, spraying… something. What’s that all about?
Those trucks are actually winter’s unsung heroes! They’re laying down rock salt or a saltwater brine solution to stop ice from forming on the roads. And fun fact: that salt? It’s basically the same stuff in your salt shaker—good old sodium chloride (NaCl). The science behind it is simple: salt lowers the freezing point of water, preventing ice from forming and keeping the roads safer for drivers.
So, next time you see those trucks, give them a little nod of appreciation. They’re the reason your commute isn’t a slip-and-slide adventure! ❄️🚗💨
