![]() PROCESS: Go to a really dark room and stand in front of the mirror. The exact reasons why particular materials show triboluminescence can be different for different materials, but it is probable that crystal structure and impurities are primary determinants of whether or not a material is triboluminescent. This isn't something so shocking since all hard sugar-based candies emit some degree of light when they're breaking, and this effect is called. Wint-O-Green or Pep-O-Mint lifesavers dark room mirror. These irregularities, or localized asymmetries, also allow for an electrical charge to collect. ![]() Impurities, disorder, and defects are also common in triboluminescent materials. Therefore, an additional characteristic must determine triboluminescence. 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. How many different flavors of Life Savers are there More than 40 flavors of Life Savers have been created since they were invented in 1912, though many have been discontinued over the years and other new flavors have been introduced. Piezoelectric materials generate an electrical voltage from the separation of positive and negative charges when they are squeezed or stretched. The flavors that are currently widely available are cherry, raspberry, watermelon, orange, pineapple, Wint-o-Green, pep-o-mint, and buttered rum. Triboluminescence is related to piezoelectricity. ![]()
