I appreciate how many times you say "but why does that happen?" "I wanna know why that is the way it is" because its so helpful when im trying to picture what's going on. I can picture everything more clearly now. everything fits together. but its still confusing stuff, especially in my college intro course, but the "why" is so important when trying to understand something

About to fail my AP Chem test tomorrow!!

I wish these kind of light-hearted and aesthetically pleasing animation videos existed for more advanced topics in chemistry, like molecular symmetry and group theory for example.

what are these words coming out of his face

I shall not rest, until I understand the content of this video! May there be lots of coffee!

Most of you are in high school chemistry... well I'm in Integrated Organic/Biochemistry and he is EXTREMELY helpful. Some college professors are horrible teachers!!!

there we have it guys, water is bent.

Eminem, you have got a huge competition.
You all listened rap God, but here comes CHEM. GOD

put the speed to 0.5 and you'll get drunk Hank explaining science.

Guys. He wanted to CHILL US OUT SO HE TALKED ABOUT ICE CLOUDS AND EUROPA'S ICY SURFACE IM BOTH SO IMPRESSED AND SO MAD.

"Weird stuff is my favourite stuff cause it means interesting questions". I found my spirit animal.

Balloons were such a good way to explain it, that fit in my mind so well

I've been watching Crash Course since sophomore year of high school. Here I am, years later with a Molecular Biology degree, studying for the MCAT, and I still refer back to your videos for quick, easy (and entertaining) reminders of foundational stuff. Thank you!

I'm in college taking chemistry. My professor is nice, but she sucks at explaining! The damn book does a better job! Still nice person lol. This did not exactly cover what was I looking for, but the information was useful.

i thought i could get slightly away from my stats class by watching chemistry, but when i saw sigma, i almost died

[lildeathpunk]

when you realize that high school chemistry is teaching you nothing

-looking at me in the eye " or mybe just try to pass a test"

[KARADemonsChild]

My AP Chem teacher tried to teach this to us in like the last 30 minutes of class. I unfortunately failed to grasp it

Today learned that a Balloon Artist would not make much of a living selling representations chemical bonds and electron orbits. Not as marketable as swards and dinosaurs.
