  [|www.webexhibits.org/causesofcolor/4AB.html] An unusual example of gas excitation is found in triboluminescence, seen when we crunch a Wint-O-Green Life Saver candy in front of a mirror in the dark. Triboluminescence translates as light from friction. In a miniaturized version of the effect of lightning, gas excitation of nitrogen in the air produces a blue-white light. As we chomp on the candy, areas of positive and negative charge are formed in the sugar crystal. When a high enough potential difference is created, electrons jump across the fractures in the crystal. They collide with nitrogen gas molecules in the air. In turn, these are excited to produce positively charged nitrogen ions, which produce a blue luminescence. Some ultraviolet is also produced, and causes the oil of wintergreen (methyl salicylate) to fluoresce with a particularly intense blue-light production. Other examples of triboluminescence are seen in diamonds, which sometimes emit light during the polishing process, and when separating certain "sticky" surfaces, such as band-aid wrappers or postal envelopes · Triboluminescence [] · You can see triboluminescence watching in a mirror while chewing on Lifesaver Wintergreen mints (with your mouth open) in a very dark room   Join Steve Spangler as he whips up a slimy colloid and wormy polymers.

While some of us watch scary movies with eyes glued to the screen, others peek out from behind a pillow just in time to see the climax of the movie. No matter how you choose to watch a scary movie, we are all enthralled by the fright, terror and horror that the products of chemistry bring to the big screen. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· **<span style="font-family: 'Calibri','sans-serif'; font-size: 11pt;">Fake Blood Recipes [] ** <span style="font-family: 'Calibri','sans-serif'; font-size: 11pt;">
