Re: Light bulbs

Put a bulb (either burned out or not) base down in a cup of water and
put it on the turntable in your microwave oven. Set it for 15 seconds
or so and watch it 'light up' as it passes through the 'hot spots' in
the oven.

Cool! And it nicely avoids the (mythical?) danger of running an oven in a
high-Q resonant state (w/too little load.)


I have some microwave-oven stuff too, including a brief discussion of
some light-bulb shennanigans. Pay particular attention to the "ball
lightning" demos. They do work! However, sometimes it takes quite a bit
of messing with them before you see a flame-glob detach from the candle
and go drifting across the upper surface of the oven cavity all by itself.
Also note the several suggested methods for mapping the pattern of the
hotspots in the main RF cavity.

One thing I've always wondered... what is the volts per centimenter in the
hot-spots of a typical oven? It might be fairly high, and this would
explain why sharp metal objects sometimes develop a case of "death by St.
Elmo's Fire". Like a blow-torch with no fuel and no gas orifice.
