Energetic Light—
Chemical Demonstration Kit
By: Tom Russo, Chemistry Teacher, Retired Milburn, NJ
Tired of chemiluminescent experiments that only last for a few seconds? Now you can demonstrate the conversion of chemical energy into light energy for nearly 10 minutes. Simply turn down the lights, combine two solutions and then listen to the oohs and aahs from your students. Our chemists at Flinn think this demonstration is unbelievable!
Concepts: Chemilumescence, oxidation-reduction.
Time Required: 10 minutes
Chemicals Provided: An activator solution and a second solution with a mixture of chemiluminescent chemicals.

Energetic Light—Chemical Demonstration Kit AP8978
A fun way to shed some light on core chemistry concepts! Using common glow sticks, students learn about chemiluminescence, pH opti- mization, acid–base chemistry, and the action of a catalyst. Compare the effervescent glow of light sticks with different chemical additives to demonstrate the nature of the chemical reaction, the role of a cata- lyst, and the effect of pH on the ionization of the reactants. Fascinating consumer-science lab activity will capture your students’ attention as you relate chemical principles to their everyday lives. An enlightening demonstration! Kit includes complete directions, student worksheet with answer key, and materials for five demonstrations.
Concepts: Chemiluminescence, pH optimization, acid–base chemistry, catalysts.
Time Required: 25 min
Materials Provided: Sodium salicylate, hydrochloric acid, sodium hydroxide, light sticks.

Fountain of Light—
Chemical Demonstration Kit
By: The Flinn Staff
An exciting two color demonstration of chemiluminescence. A mixture of solutions is prepared, the lights are dimmed, and hydrogen peroxide is added. The mixture first glows red and then, amidst vigorous frothing and evolution of heat, an eerie blue glow appears. You won’t be able to wait to show off this spectacular demo!
Concepts: Chemiluminescence, oxidation-reduction.
Time Required: 20 minutes
Chemicals Provided: Fountain of Light Solution, potassium carbonate, formaldehyde and hydrogen peroxide solution.
Note: A large demonstration tray is recommended.
