Salty Water Chills Your Drinks In No Time
If you want to chill your beer quickly, try this: fill a cooler with water, ice cubes, and salt. Don’t worry about overdoing the salt. Without shoving them too close together, place your beer bottles into the solution. They should chill within five minutes.
If you want the science behind this hack, here it is. Every liquid has a “freezing point depression,” or a minimum temperature in which it freezes. Typically, water freezes at 32°F. But if you mix salt in water, it lowers the water’s freezing point. This is because salt’s ions prevent the molecules from crystallizing easily.
