Chemystery of Halloween—
Multi-Demonstration Kit
By: Diane Burnett, Retired
Purdue University, West Lafayette, IN
Demonstrate that “black magic” has a scientific basis with the seven demonstrations included in this kit.
• “Ghosts and goblins” will appear out of a 2-liter pop bottle as the pop bottle collapses to prove their escape.
• An “amorphous monster” will foam up and out of an ordinary cup.
• “Evil spirits” will erupt from a jack-o’-lantern.
• Eerie lights will be given off by a mysterious solution and an ordinary
candy.
• A fluorescent “slime monster” and a Silly Putty®–type material will be concocted as your bewitching finale.
Demonstration Notes and enough chemicals are provided to perform all seven demonstrations, seven times each.
Concepts: Catalysts, decomposition reactions, exothermic reactions, heat shrinking plastics, polyurethane foam, polymers, oxidation–reduc- tion reactions, fluorescence, chemiluminescence, triboluminescence. Time Required: One full class period
Chemicals Provided: Manganese dioxide, hydrogen peroxide, poly- urethane foam system, sodium iodide solution, energetic light solution, potassium ferricyanide solution, guar gum, sodium borate solution, fluorescein dye, Elmer’s Glue-All®.
Note: Some common household items and laboratory equipment are required but not provided.
A Christmas of Chemistry—
Multi-Demonstration Kit
By: The Flinn Staff
Make the holiday season joyous with seven chemistry demonstrations guaranteed to amuse and enlighten the entire class.
• Mix two clear liquids and produce a “snowfall” of white flaky precipitate.
• Make two solutions of holiday green and red and watch as they suddenly switch colors.
• Miniature paper trees are placed in crystal growing solutions to create a forest of snow-covered firs.
• A triangle of copper, a drop of silver chloride, and presto, the world’s smallest Christmas tree grows before the class’s very eyes.
• Warm the holiday season with a cozy Yuletide fire of red and green.
• Discuss saturation and solubility while welcoming Santa Claus’s arrival in a snowstorm.
• Use “disappearing ink” to write an invisible holiday greeting that, when sprayed with a dilute basic solution, reveals the message in red and green.
Concepts: Solubility, precipitation, solvation, gels, crystal formation, atomic emission, oxidation–reduction, clock reaction, buffers, acids and bases, indicators.
Time Required: One full class period
Chemicals Provided: Potassium sulfate, isopropyl alcohol, sodium chloride, bluing solution, ammonia solution, calcium acetate, ethyl alcohol, lithium chloride, boric acid, benzoic acid, silver nitrate solu- tion, formaldehyde solution, sodium sulfite, sodium bisulfite, indicator solutions, and sodium hydroxide solution.
Note: Some laboratory equipment is required but not provided.
