Jon, I did indeed "burn" a CD in the microwave.The time has to be real short. I've got an older one with mechanical timers so I couldn't be sure of an exact time but the 5 seconds called for should be about right. I think mine was about 10 seconds.

You get blue flashing at first then a silver white. It looks like the blue is what you want.After my last post I stuck the same CD back in and only got the silver-white with smoke ths time.When I pulled it out,instead of having more arc paths it seems there were more holes.Also, since I didn't have a paper cup I used a shot glass to support the CD.

Another trick to try is to take a pint beer glass filled with water,put a light bulb in it base down, and microwave it.The bulb will light up without harming the microwave.

Now to try the plasmoid experiment.

Oh, and now we return you to Larry's thread which is still in progress.
