##### 点评

You can not use very casual natural language. 

You may need some practice before using it very well.

Free plan is enough for daily usage.

##### Intro

He is a YouTuber, the channel is not too much about school lessons. But more about interest. There are many famous and fun Chemistry experiments, such as turn toilet paper into alcohol.

You may get some idea about your EE or IA as your common sense got challenged.

##### Info

> Capturing the natural beauty of chemistry
> 
> I find that chemistry is often taught poorly or without a purpose. Because of this, people tend to lose interest and sometimes even start to hate it. In each video that I make, I try to balance theory with purpose. My goal is to capture the natural beauty of chemistry in fun and interesting ways.
> 
> In terms of education, I have a BSc in Biochemistry, with a minor in pharmacology. However, I've always been a lot more drawn to applied chemistry. So after finishing my degree, I worked as a lab tech in an organic lab, and then as a chemistry grad student. However, I ended up leaving my graduate studies early to focus on this channel. Now, making chemistry videos has become my full-time job!
