"nitrate" news and stories

I recently came across a Popular Science article about candy rockets, model rockets that use sugary foods like Pixy Stix and Oreo filling as their fuel. By adding an oxidizer like potassium nitrate or potassium perchlorate to the sweet stuff, you can get it to burn with the speed and intensity needed for things like launching a small rocket. The Popular Science article features a link to a page of "Candy Propellant Experiments," with descriptions, photos and video of rockets fueled by Snickers, Oreo creme and Pixy Stix. There's also a link to another group that's in the process of trying to launch a sugar-powered rocket into space.
