If you need to chill a bunch of warm beer for your Fourth of July party, here’s the fastest way to do it and you can also turn this into a summer science lesson for your KID if you want. That way you’ll look like a good parent and have a beer or two to celebrate!
According to Popular Science, the best way to chill a beer super-fast involves salt water SO get to an ocean! Well, not really, but salt water WILL get the beer (or other beverage) colder faster. If you want all the details as to why, read on!
You see. even without salt, ice water cools down a beer faster than just ice because the water completely surrounds the can but SALT water works even better because it freezes at a lower temperature. Especially if you use a lot of salt.
Normal water freezes at 32 degrees but really salty water won’t freeze until it’s about five below zero. Basically, it’s because the sodium molecules get in there and prevent the water molecules from forming into crystals.
Now, ice actually melts faster in salt water but don’t let that fool you. It’s not because the salt is raising the temperature of the ice. It’s just converting the ice into salt water that’s still the same temperature which is right around 32 degrees.
If you add even more ice to the mix, the temperature of the water will keep dropping but won’t freeze. So, you can get it down to something like 25 degrees instead of 35 and that extra ten degrees is huge.
In normal ice water, it takes about 15 minutes to get your beer down to a perfect 38 degrees but in really salty ice water, it should only take about five.
