朗读Edward Rawn
As an experiment, go out and buy two identical bags of potato chips.
我们做个试验，去买两包一模一样的薯片。
In one of them, use a needle to carefully poke a hole near the corner, and gently squeeze the bag to let out a lot of the air through that hole.
把其中一包用一根针在边角的地方戳个小洞，慢慢把袋子里的空气挤出来。
Now find a friend and spend 5 minutes playing "catch" with each bag, tossing it back and forth between you across the room.
找个小伙伴花5分钟把这两包薯片来回扔。
Get two large bowls, and pour the contents of each bag into one of the bowls.
拿2个大碗，把2包薯片拆开分别倒在碗里。
In one bowl, every chip is broken into small pieces. It's almost a bag of crumbs, not a bag of chips. This was the bag with not a lot of air in it.
其中一个碗里的薯片都碎了，成了薯片碎屑。这是那包被放了气的薯片。
In the other bowl, there are a few broken chips, but overall many more chips are still in good shape. This was the bag full of air.
另一个碗里的薯片虽然有几片碎的，但总体完好。这包是充了气的薯片。
The air trapped in the bags help cushion the chips during transportation and handling, so that a better product is delivered.
这就说明包装袋里的空气在薯片在运输过程中，起到了“垫子”的作用，让薯片不易碎。
