Hello, I saw http://video.google.nl/videoplay?docid=6732382807079775486&q=microwave" [Broken] experiment on Youtube , and I was wondering what reaction is going on here. I also saw a variant of this (can't find the video though), in which the plasma existed for 57 seconds, when it changed colour to blue with some white sparks in it, a few seconds before dissolving. Does anyone know why it changed colour? Thanks in advance! If I I posted this in the wrong subforum, could an admin move it please?
