• 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.
Teacher 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–reduction reactions, fluorescence, chemiluminescence, triboluminescence.
Time Required: One full class period
Note: Some common household items and laboratory equipment are required but not provided.

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
