It's not a great plan to run your microwave with nothing in it except for the CD. Close the microwave door and nuke the CD for a few seconds. Do not microwave the CD for an extended period of time (more than a few seconds is too long). You'll see a glow and sparks almost as soon as you turn on the microwave. Allow the CD to cool before removing it.
