Magnesium is one of the most commonly used structural metals, being light and strong. It's necessary for living cells. And was used in early flash photography. But what you really want to know, is it 'splodey? Let's find out!! Oh, and there are also special appearances by "Chris Crocker" and the "Cookie Monster" (both impersonations done badly by me) as they drag you kicking and screaming through a few Internet Memes of 2007.
You can refer to WebElements (http://www.webelements.com/magnesium/) for more on Magnesium. Or just use Google, silly.
Special thanks goes out to Martyrd (www.myspace.com/martyrd) for the use of "Blue and Black" in this video, and to Andrew (www.myspace.com/morbidcaffienejunkies) for being an excellent camera-using minion.
