Is it possible for a potato to catch fire after 10 minutes in the microwave?
"Should be fine" is like saying 'well, there's really low odds of something going wrong'.  I have no idea what the odds are, but yes, it's possible.

I had microwaved potatoes many times, and then had a rather strange incident that I described in another question about microwaving potatoes, and included links to other incidents of people mentioned it happened to them.

I've since had a few years to think about what happened, and there's a few possibilities besides what I originally mentioned:


I don't know how old the potatoes were.  They might've been older and a little bit dry.
I was half asleep, and it's possible that I didn't poke them a few times.  I don't know if that could've led to the skin separating from the meat of the potato and that drying out &amp; catching fire.
