Characterization of Organic Illumination Systems http://research.compaq.com/wrl/techreports/html/TN-13/pickle.html Tongue-in-cheek technical report on the phenomenon of electroluminescence in pickles, with apparatus diagrams and plots of current and temperature versus time. The practical applications of glowing pickles are also explored. Electric Veggies http://www.geocities.com/CapeCanaveral/Cockpit/8107/ElectricVegg.html Attributes the origins of the glowing pickle demo to the children of Catherine Ireland, a chemistry teacher from Manhasset High School of New York, in July of 1987. Glowing Pickle http://isaac.exploratorium.edu/~pauld/activities/aaptelectric/glowingpickle.html Two enhancements to the standard demonstration apparatus: using a ground fault interrupt (GFI) to reduce the risk of electrocuting the demonstrator, and using potassium chloride (a dietary salt substitute) to produce a pink glow rather than the traditional sodium yellow. Also discusses the mechanism of the single-ended glow. Glowing Pickle http://www.sfu.ca/physics/ugrad/courses/teaching_resources/demoindex/eandm/em5d/pickle.html Short description of the science demonstration, with annotated bibliography of print references. From the Simon Fraser University Physics Department lecture demonstration index, classification PIRA 5D30.30. Journal of Chemical Education: Glowing Veggies http://jchemed.chem.wisc.edu/Journal/Issues/1996/may/abs456_1.html Abstract of article extending prior work on glowing vegetables to non-sodium ions. Intended as an aid to science classroom demonstrations. Journal of Chemical Education: The Incredible "Glowing" Pickle and Onion and Potato and... http://jchemed.chem.wisc.edu/Journal/Issues/1996/may/abs456_2.html Abstract of article on electrical conductivity in foods. Intended as an aid to science classroom demonstrations. Lori's Chemistry Page http://www.geocities.com/CapeCanaveral/Launchpad/6603/glowing.html Discussion of various wavelengths of light, comparison of the colors of potassium, sodium, and lithium flames, and QuickTime movie of a demonstration of these concepts, by a high school chemistry teacher. Also has instructions on how to make a glowing pickle. Net4TV Voice: Surfari: Electric Pickles http://net4tv.com/voice/Story.cfm?storyID=3329 A personal anecdote from Mr. Wizard's housekeeper, with reviews and descriptions of many sites describing the glowing pickle trick. Shady Hollow http://members.tripod.com/~Shady_Hollow/Projects/gpickle.html Details how to build a glowing/flaming Pickle. Includes photos of the apparatus using heavy-gauge wire and glass jars as insulators, and a plugged-in pickle glowing only at one end. The Electric Pickle as Will and Idea http://ygraine.membrane.com/hubris/notes/electric_pickle.html Philosophical discussion of the meaning of the experiment, and multimedia files (.AVI, .MOV, .WAV) of the results. Useless Information: The Electric Pickle http://members.tripod.com/~earthdude1/pickle/ The tale of a teacher in search of compelling classroom demonstrations. Also discusses, but does not explain, a demonstration where he set his tie on fire to satisfy a student's repeated requests. X Magazine: Please Pass the Science http://www.cardhouse.com/berk/science99_3.htm Reader feedback with a list of precautions to be taken when electrocuting pickles, of more humorous than practical value. X Magazine: Please Pass the Science http://www.cardhouse.com/x10/x10science.htm The Glowing Pickle: Born of Boredom. Essay on discoveries made by bored scientists, from Post-It Notes to pickle-based sodium arc lights.
