It's not so much the experimenting that matters, just the quality of
observation.

But there has to be something to observe, so it is not
clear what you have in mind.


Past experience. :) What I do is look at anything, it might not reveal a
useful point at the time, but anything recalled later when searching for
clues or ideas helps. The various times I've tried to dry stuff in any way,
the one common flaw was in extracting vapour from a confined space. Even
with the fan, a working microwave can have vapour condensing on the walls,
and it won't insulate against heat very well, it wasn't built with that in
mind, as the contents absorb energy directly and heat doesn't get out to
the walls that easily, let alone beyond them. That set of observations led
me to think a microwave case would be good as a slow drier only, and even
then, dependent on low ambient humidity and a lot of local heat for extreme
drying.

If I needed an extreme drier in a self-contained case I'd probably buy a
cheap portable dehumidifier and put in in a small cupboard with the stuff
to be dried in front of its fan. I've got one and tried it, it's
astonishing, far better than heat alone, and with far less energy used too.
