1
Here's a fun experiment you can do with the kids.
2
Let's do an experiment together.
3
I promise it'll be quick.
4
I want to make chloroform for my caffeine extraction, but my parents' house doesn't have any lab equipment.
5
So this is my beaker.
6
I found it on the street.
7
First, make yourself a measuring cylinder and prepare exactly 30 acetones.
8
Take your bleach out of the freezer and mix them together.
9
Don't try this at home.
10
Chloroform is being produced, so I am upwind to keep me safe from the toxic fumes.
11
I checked the next day and collected the bottom layer of chloroform.
12
To purify this, use a distilling setup with a heating mantle.
13
I don't have that, but I do have this random glassware I found at the thrift store to make into a simple still.
14
That's so cool.
15
Now pour some water and transfer it to a water bath underneath the apparatus.
16
Now you can see it condensing pure chloroform into the centerpiece.
17
What did I tell you guys about playing with chloroform again?
18
I need to test its purity, so I've prepared a lethal cocktail of chloroform.
19
Come on, wake up.
20
Taste test.
21
Mmm, yum, chloroform.
22
You can have some too.
23
Mmm, chloroform.
24
I'd say that's like a 9 out of 10 right there.
25
No one was hurt, that's water, is it?
26
I did make chloroform this way though, which I'll use next video to see if I can caffeinate anything I want.
背景與上下文
在這個視頻中，講者分享了一個有趣的家庭實驗，即在沒有專業實驗室設備的情況下製作氯仿。雖然音訊聽起來輕鬆愉快，但實際上這種化學品具有潛在危險性，並且不適合在家中進行。想了解如何正確地使用語言來表達實驗過程，並掌握科學相關的英語表達嗎？這段視頻提供了豐富的學習材料，讓你在輕鬆愉快的情境中進一步提高英語口說及發音技能。
日常交流的五大短語
- 讓我們一起實驗。 - A great way to invite someone to participate in an activity.

- 不要在家嘗試。 - A cautionary phrase that advises against unsafe activities.
- 看看這個凝結純氯仿。 - A phrase that describes the observation of a scientific process.
- 我需要檢測它的純度。 - Important when discussing measurements and experiments.
循序漸進的模仿指南
若想提昇自己的英語發音，shadow speech是一個有效的練習方法。以下是如何利用本視頻的步驟：
- 首先，觀看整個視頻，注意講者的語速和語調。記住，提高英语发音的第一步是聽得清楚。

- 作為最後一步，錄音你自己的模仿，然後與原視頻進行對比，反覆調整以達到最佳效果。
透過這種方式，你將會逐漸掌握氯仿的科學背景與相關語言，並在日常會話中自信地運用這些短語和技巧。如果你有興趣進一步精進自己的shadow speak能力，不妨將上述方法與更多視頻結合，深度提升自己的口語能力！
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
