This video started a good discussion over on my friends feed. So far no one has answered it and I dont want to give away the answer to anyone else (please CW your answers) but the question is this:
Why is it when you burn a piece of steel wool it gets heavier, but if you burn a log it gets lighter.
@freemo Burning a log creates water vapor that is released into the atmosphere? 
Follow
@DuchessOfMars that is a small part of the answer, but not the majority of it.
