Nuclear bomb video

While researching the background for a superhero roleplaying game, I came across a bunch of information about the Hiroshima and Nagasaki atomic bombs. I stumbled across this video.

It's just nuclear explosions set to heavy metal music. Truthfully, it could do without the music. The images themselves are stunning, in their horror and their beauty.

There are some images that don't look like they belong. They look like big balls of ooze, slowly expanding. That's the core of a hydrogen bomb, expanding in the very, very early stages of the explosion. The footage was taken with an ultra-high speed camera. The bulk of the camera was situated over a mile away in a hardened bunker. I can't remember the specifics of how the camera worked, but it was able to catch the very first microseconds of the blast. I've seen stills from that footage, but not the motion pictures.
