While we're on fun experiments you can do at home, has anyone ever done the triboluminesence bit? Apparently, if you pop a wintergreen lifesaver (gotta be wintergreen, according to the pros) in your mouth facing a mirror in a darkened room and bite down on it with your mouth open, you should see a flash of light. I invested in two rolls of lifesavers with disappointing results. But triboluminesence is a real phenomenon and a physcist tells me there's no reason it shouldn't work. [honest emoticon]
