Hi, everyone, Squeaks and I just finished doing some cooking over in the kitchen,
嗨，大家好，我和吱吱刚在厨房里做完饭，
we wanted to make some delicious onion soup.
我们想要做些美味的葱头汤。
And while we were chopping the onions for it, we noticed something strange happened.
当我们为了做汤切洋葱时，注意到某些奇怪的事发生了。
I started to cry, Squeaks was worried that I was upset, but I wasn't crying because I was sad.
我开始流泪，吱吱担心我难过了，但我不是因为伤心才哭的。
My eyes were just tearing up because of the onions.
我的眼睛流泪是因为洋葱。
It's totally normal for chopping onions to make people cry, even if they're really happy and having a great day.
切洋葱使人流泪很正常，即使他们非常高兴、心情愉悦。
And that's because crying isn't only for when you're feeling sad.
这是因为人们不只伤心时才会哭泣。
Your eyes also make tears when they're dry, itchy or uncomfortable to help them feel better, and stay healthy and strong.
你的眼睛发干，发痒或者不舒服时也会流泪，这会帮助它们更舒服健康。
That's what happened while we were cooking.
这就是我们做饭时发生的事。
Something about chopping an onion was bothering my eyes.
切洋葱时某些东西刺激了我的眼睛。
Sometimes things called irritants, stuff like dust, dirt or chemicals in the air can irritate and bother our eyes.
有时叫做刺激物的物质如空气中的灰尘、污垢或化学品会刺激我们的眼睛。
Irritants make eyeballs itchy, dry and just generally uncomfortable.
刺激物使眼球发痒、干涩、不舒服。
And we can't use our hands or a towel to get them out because our eyes are really sensitive.
我们不能用手或毛巾将它弄出来，因为我们的眼睛很敏感。
Luckily, for us, eyes come with a built-in cleaning system, tears,
幸运的是，我们的眼睛自带清洁系统——眼泪，
which were kind of like a special washing machine for your eyes.
它有点儿像眼睛的特殊洗衣机。
Tears contain a lot of water, which mixes up with any irritants in your eyes that are bothering them.
眼泪包含很多水，与你眼中扰人的刺激物混合着。
Then the tears make their way to the corners of your eyes, up and over your eyelids and out of your eyes entirely.
然后眼泪流到眼角，越过眼皮，直到完全地流出来。
That's when they roll down your cheeks, taking the irritants with it.
当它们从你的脸颊上淌下来时，也带着刺激物一起流下来。
Crying helps your eyes to feel much better, much faster, even if you aren't sad.
即使你不伤心，眼泪也会使你的眼睛更舒服，恢复得更快。
Sometimes if your eyes still hurt, a little running water can get any left-over irritants out.
有时，如果你的眼睛仍然疼痛，流水可能会把所有残留的刺激物清除出去。
I think I'm okay now and I don't need any running water.
我想我现在好了，不用流水了。
But I'm still curious about what part of the onions was causing my eyes to tear up.
但我仍然好奇是洋葱的哪个部分让我流泪的。
Good idea, Squeaks! Let's try it! we've got an onion here and my eyes aren't watering.
吱吱，好主意！我们试试吧！我们这里有个洋葱，我没有流泪。
The outside of the onion is dry and not too smelly. And my eyes feel fine so far.
洋葱的外部是干的，不太难闻。我的眼睛目前很好。
But if we cut it open, something changes.
但如果我们切开它，事情就变了。
See, there's a bit of juice that came out and a very powerful onion smell.
看，里面有一点儿汁液流出来，还有一种非常强烈的洋葱味儿，
And now my eyes are starting to tear up a bit, too.
现在我的眼睛又开始流泪了。
I know, it's because of the juice.
我知道，这是因为汁液。
Once we cut open the onion, tiny bits of the juice can spread around in the air.
一旦我们切开洋葱，少量的汁液就会扩散到空气中。
That's why it starts to smell more.
这就是它开始闻起来气味变强的原因。
The juice floating around in the air gets into your nose.
漂浮到空气中的汁液进入你的鼻子。
That also means it can get into your eyes.
那么它也会进入你的眼睛。
And since the onion juice is an irritant, your eyes start to tear up to get rid of it.
因为洋葱汁是刺激物，你的眼睛开始流泪来清除它。
It's starting to bother my eyes now, but it isn't too bad.
它现在开始刺激我的眼睛了，但还不是太糟糕。
There are lots of ways to stop the onion juice from getting into your eyes, though.
不过，有很多方法我们阻止洋葱汁进入眼睛。
Some people like to put onions in the refrigerator before cutting them, or soak the onions in water first.
一些人喜欢在切洋葱前把它放入冰箱，或者在水里先浸一下。
That can help by lowering the amount of juice that gets into the air when you finally cut open the onion.
这可能帮助你最后切洋葱时，降低进入空气中的汁液量。
Squeaks, do you have any other ideas?
吱吱，你还有其他的办法吗？
That's a great idea! We can wear our lab goggles.
好主意！我们可以戴实验室护目镜。
Yeah, you know, cooking is just like doing a science experiment.
你知道的，烹饪就像做一项科学实验。
Just like some kinds of scientists,
和一些科学家一样，
we combine different things carefully, measure out certain amounts and mix them up in all sorts of ways to create something new.
我们小心地融合不同材料，测量一定的量，用各种方法把它们混合起来，创造出新的东西。
And in this case, it's delicious.
在这种情况下，它非常美味。
If we're going to be kitchen scientists, dressing the part and wearing our goggles is lots of fun.
如果我们要成为厨房科学家，着装得体、戴着护目镜一定很好玩。
If you want to try this for yourself, ask a grown-up for help cutting open an onion,
如果你想自己试试，叫个大人帮忙切一颗洋葱，
and see if one of these ideas keeps your eyes from tearing up.
看看这些办法是否能阻止你流泪。
