When you're the one making the rules, you don't normally screw yourself in the process.

如果你本身就是制定规则的人，通常你肯定不会让自己深受其害。

Deep-breathing techniques can also help, as can watching a video-tape of yourself (to see for yourself that you didn't screw up).

做一下深呼吸也会有所帮助，你还可以预先演练一遍然后录下来，这样你就可以看到你并没有搞砸。

Get yourself a few screw-top or Kilner-type jars, making sure the tops don't have any exposed metal that will react with the vinegar (plastic tops are perfect - provided they seal properly).

取一个旋盖的或者kilner式的罐子，盖子上不可以有暴露的金属，因为金属会和醋起反应(密封性好的塑料盖子最好)。
