Rules:) How many CD's have you burned in your microwave oven? And have you build your own Tesla trafo? If not, then give them a try also...

What if you DON'T heed the warnings...

The page has a bunch of warnings saying that you shouldn't keep the microwave on for more than 10 seconds because the glass container is getting hot... If you do and it melts the glass, will it attack the ceiling of the microwave itself next? =)
Anyone have a spare microwave they don't mind sacrificing to see what happens if you just keep it going?:) (don't forget to document and give us a link!)
Just as much fun...

Take a non conductive container and fill it part way with water. Take your standard every day 60 Watt light bulb and submerge the threaded end into the water. Put the container into the microwave & turn it on.
Fun light show...wheee!
Tons of interesting stuff

There's tons of interesting research on that site, like field effect propulsion and antigravity. Check http://jnaudin.free.fr/advpmnu.htm
what exactly is 'plasma'

i may have missed something in the article, but when does a substance qualifies to be a 'plasma'? It sure looks nifty but that can't be a criterium, right?

We used to build plasmoid balls as physics demos for kids. My professor said it isn't bad on the microwave either.
Instead of building that complex machinery list at the webpage all you need is a standard 2-liter bottle of soda (pop for Midwesterners, coke for Texans). Cut the bottom off and discard the top (usually about 3-4 inches should do) poke hole in the side for airflow.
Now you need something to hold the match upright e.g. a.b.c. gum or a cock like them.
Light the match close the door, start the microwave. Eventually your 2-liter will melt causing even more fun.
I've tried this several times with varying degrees of sucsess. For those of you with plenty of time, try repeating the experiment with a glass container not given enough ventilation. When the plasmoid ignites (lights? is born? stabilizes?) it radiates a lot of heat. Without proper ventilation the glass vessle will jump upwards with a satisfying bang. The flash is quite impressive for the easily amused.
As for the sound, there is some sound produced other than the low pitch hum of the microwave itself, sort of a buzzing noise.
I once saw a page describing this experiment, but this person had taken the magnetron tube out of the microwave, mounted it in a very sexy looking raygun type configuration. It looked exceedingly dangerous. I'm sure all the reflected radiation was an excellent stimulation to his fertility.
Such wonderful toys.

Ok, curiosity was stronger than worry:
Third attempt: more or less same setup as previously, but a little less water in the "load" glass, and using a larger cork, so that the mine could stand upright without leaning against the bottle. A spark appeared already early on in the experiment, but didn't cause a ball. However, the same candle-flavored fumes started appearing again. Then it hit me: they came from the cork, which was heated by the pencil mine stuck into it. Indeed, the cork had small traces of burn. Still no plasmoid, alas.
Fourth attempt: Figuring that strength of microwaves might depend on orientation, I broke a small piece off the mine, and stuck it into the cork, horizontally, rather than vertically. Soon indeed sparks, and then a ball of fire appeared, but unfortunately the pleasure was rather short-lived: the plasmoid set fire to the plastic bottle, and thus I had to stop the mess. Ok, I'll have to hunt for a suitable glass vessel.
