Simon Brunning points out a page about Unsafe Microwave Oven Experiments. Looking at the plasmoid and ball lightning sections of that site got me to try this Google experiment: do a search for the words plasmoid microwave cigarette and (today, anyway) you'll get my "Nuking lit carbon yields plasmoids" weblog page from last October.
The scary part is the (one) other page yielded by that search, a bizarro paranoid rant that I'm leery of linking to from here. 11:43:35 AM comment/
