How many times have you wanted an ice cold beverage and realized you didn’t have anything already chilled in the refrigerator? Education.com has the perfect method to cool down your beverage whenever you run into that problem – a salt water ice bath!

Why does that work? Apparently, salt will help lower the freezing point of the water to allow the ice in the ice bath to melt while keeping its temperature. Plus water is a better heat conductor than the air in your freezer, so the heat will leave your beverage faster.

Don’t believe the experiment? You can try it on your own. Experiment by putting a beverage in the freezer and in an ice bath and see which one get cooler faster.
