Why I Love The Internet, Reason #956

This guy has done what I (and probably every other guy in my high school chemistry class) wanted to do when we learned about elemental Sodium's behavior when it comes into contact with water.

The site has multiple videos of the various explosions these guys created with three and a half pounds of the metal, but this one's my favorite (4.7MB).

Enjoy.
