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!

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.
