I like to imagine that we are all familiar with School House Rocks and their educational short films. Really, who can forget the Bill on Capital Hill?! The creators managed to take a rather dry subject and turn it into a short animated film that was just long enough to be informative but not so long that your attention would waver. While School House Rocks is no longer creating new material, Crash Course has taken up the mantel and is making short, informative films on a variety of subjects from astronomy, to chemistry to US history and politics. My favorite is the series on Astronomy! So inject a little knowledge today the fun way!
