Today, I'm gonna show you a really quick way to cool down your drink. And we're gonna use a pack of room-temperature lemonade. As you can see, at room temperature, they're 24 degrees Celsius—that's 75 degrees Fahrenheit.
今天，我要來教你一個超快就能讓飲料變冰涼的方法。我們會用到一組常溫檸檬水。如你所能見到，在常溫下，檸檬水的溫度是攝氏 24 度－－也就是華氏 75 度。
Start by putting a bit of water in a bowl and top it up with ice, like this. Next, sprinkle over a couple of tablespoons of cooking salt, give it a good mix; then go ahead and put your can in. Basically, adding salt causes the ice to melt faster. But to do this, it needs to draw heat energy from wherever possible—in this case, out of our can, causing the drink to rapidly cool down. Pretty cool, huh?
After a minute, give it a good stir. You can pretty much use this method for any canned or bottled drink. After a couple of minutes, take the can out, and let's see how it compares to the one from earlier. If you remember, at room temperature, it was 24 degrees C—that was 75 degrees Fahrenheit. And after just two minutes in the ice and salt solution, you can see the temperature has dramatically dropped, all the way down to five degrees C—that was 41 degrees Fahrenheit. That's a total drop of 19 degrees Celsius, or 34 degrees Fahrenheit, in just two minutes, leaving you with the perfect temperature to serve a nice cold ice-cold lemonade.
一分鐘後，認真攪拌一下。這個方法幾乎可以運用在任何罐裝或瓶裝飲料。兩分鐘後，將罐子拿出來，我們來看看它和原先飲料的溫度有什麼差別。如果你還記得，在常溫下，飲料溫度是攝氏 24 度－－也就是華氏 75 度。而在冰加鹽溶液中僅僅兩分鐘後，你可以看到溫度大幅下降，一路掉到攝氏 5 度－－華氏 41 度。那就是總共掉了攝氏 19 度，也可以說是華氏 34 度，只在兩分鐘內，讓你有超剛好的溫度送上一杯透心涼的檸檬水。
