Friday's Education Video Roundup (8/29)

I'm an educational video fanboy and it's a major bummer that my current work keeps me from spending hours watching all the new videos coming out.  However, I'm going to try to put out a weekly roundup of the best videos from the week.  Without further ado, here are some of the best:  

How do stones move in the desert? 

How does a bean become a fart? 

What's the value of the Earth?

What happens when I drink coffee? 

How will packages be delivered in the future? 

Why do we draw stars the way we do?  

Am I next? 

It's important to end with a smile... Don't share this one with your students. :)
