Very clever method. However, it may work only with microwaves from which you've removed a turntable. Those without a turntable to begin with will have some other mechanism inside to distribute the radiation uniformly. (Makes me think of Leslie speakers.)

It amazes me how people figure this stuff out.

Elegant use of the standing wave in a tuned chamber. :D

My experience is that microwaves tend to have one or two hot spots. I base this on the dessicants that turn color when they dry out, so much less sensitive than the melting of marshmallows. I'll have to try this. I have no doubt that it works, since this was submitted to American Journal of Physics (an educational journal).

One question jumps out at me -- this requires a standing wave; anyone know why there would be a standing wave in the oven?
