How do refrigerators work?

I've always wondered what keeps my beers cool and my cheeses fresh. Now I'm new to Instructables, but on the advice of a good friend, I thought I'd post this here:
 

I love to figure out, research, how stuff works. And then figure out how to tell that story. This one animation has a bit of a story itself, because it turns out I made the first version a bit too fast... I didn't do my research properly. Anyway, so here it is. I'm curious to know what you think!

ask people who don't know.

with the info bubble pop ups, its a bit overwhelming how quick info is coming. Cant absorb it all.
