You may have noticed that Tuesday of this week marked the 200th Question of the Day that has appeared here on Stuff.dewsoftoverseas.com! I would like to first take a moment to thank everyone who has submitted questions, as well as all of the people who have written in with comments, suggestions and thanks for the questions in the question archive.
Answering the Question of the Day each day has is a great experience for me. I truly enjoy it, and I get to learn something new every day. As of this moment, 16,757 questions have been submitted - it is absolutely amazing to go through the new questions that arrive each day. The breadth and variety of the questions asked is incredible!
To celebrate the 200th question I would like to turn the tables and ask you, the readers of Stuff.dewsoftoverseas.com, to help me with a set of questions that I have been unable to find authoritative answers for! These questions, by the way, show up in the question box with some regularity so I would like to get them answered. Perhaps you, or a person that you know, would have access to the answers to these mysterious, impenetrable queries! Some are silly and some are serious, but in all cases I am looking for an expert who can illuminate us all. Here they are:
If you have an authoritative answer to any of these, please discuss your thoughts in our Question of the Day Forum.

- From at least 10 different readers: "Years ago in [pick a place] I saw a small kitchen device used to light gas burners on a stove. It consisted of a small wooden handle and a wire, about 16 ga. protruding from it. The end of the wire a few inches away from the handle was loosly coiled into a spring configuration about 1/2 inch or so in diameter. Inside the coil was suspended a thin wafer of some material. One placed the coil in the stream of gas from the burner and it lit the burner in a few seconds. No spark that I saw. Eventually the device lost some of its "power" and the flame took longer to light. To recharge it you simply placed it in the open flame for a minute or so and like magic it worked well again. Have you ANY idea how this works? "
