Many cultures celebrate the new year with fireworks, but few revelers know much about the chemical reactions that stoke these bright displays. Each blaze and boom is the result of carefully choreographed oxidations and reductions, with metal salts producing the colors. Your pyrotechnic engineers will sparkle in this month's Harry Potter-themed lab activity. Happy 2015!

Activity: Wizardly Wands
High school students learn such core chemistry concepts as reaction rates and thermodynamics by making and demonstrating their own Harry Potter-style "magic wands" (sparklers). The lab, which also can serve as a fun AP course review, concludes with a class duel between wands of two different chemical compositions.
