These irregularities, or localized asymmetries, also allow for an electrical charge to collect. Impurities, disorder, and defects are also common in triboluminescent materials. Closing the door, you wait five minutes or so - for the friends eyes to adapt to the dark - then pop a few Wint-O-Green Life Savers into your mouth and begin chomping away. Therefore, an additional characteristic must determine triboluminescence. THE ELECTRIC LIFE SAVER EFFECT Kids have been familiar with this spark-in-the-dark magic for years. However, about a third of known triboluminescent materials are not piezoelectric and some piezoelectric materials are not triboluminescent. Asymmetric, piezoelectric materials are more likely to be triboluminescent than symmetric substances. An asymmetric molecule changes its ability to hold electrons when squeezed or stretched, thus altering its electric charge distribution. Sucrose molecules and crystals are asymmetric. Piezoelectric materials generally have an asymmetric (irregular) shape. Piezoelectric materials generate an electrical voltage from the separation of positive and negative charges when they are squeezed or stretched. at my summer camp we would walk in to the forest tell ghost stories and then do spark in the dark. Triboluminescence is related to piezoelectricity. A dark room with a mirror Wintergreen Lifesavers.
