Instant Light—
Chemical Demonstration Kit
By: Rhonda Reist
Olathe High School, Olathe, KS
Add a few teaspoons of Instant Light crystals to water and watch as the solution immediately produces an eerie blue glow that will last for several minutes. Instant Light is a mixture of dry chemicals, including luminol, that when added to water produce chemiluminescence. Save valuable preparation time and create a lasting memory for your students. Concepts: Chemiluminescence, oxidation-reduction.
Time Required: 5 minutes
Chemicals Provided: Instant Light crystals.
Note: A completely darkened room is necessary for this demonstration.

Let There Be Light! Chemiluminescence Demonstration Kit
By: The Flinn Staff
Captivate students’ attention with four “enlightening” demonstrations about chemiluminescence! First, when light is produced without heat, that’s cool! Pour two solutions together to illustrate the light-producing reaction that takes place when luminol is oxidized. Then, astonish students with Energetic Lights’ ability to exhibit luminous longevity! Next, students will be de“lighted” as the solutions appear a different color when exposed to black light. Finally, observe the different color light produced as various salts are heated to their excited states. Concepts: Chemiluminescence, oxidation–reduction, catalysts, fluo- rescence, absorbance, transmittance, emission, excited versus ground states and atomic emission.
Time Required: One full class period
Chemicals Provided: Calcium chloride, copper(II) chloride, energetic light solution, eosin Y solution, ethyl alcohol, fluorescein solution, hydrogen peroxide, luminol, potassium ferricyanide, rhodamine B solution, sodium chloride, sodium hydroxide solution and tonic water.
Chemiluminescent Chemical Reactions in a Model Volcano— Chemical Demonstration Kit
By: The Flinn Staff
Try this amazing demonstration! Construct a model volcano using poly- urethane foam, and then produce a fiery lava flow using the decomposition of hydrogen peroxide and light stick chemicals. An awesome display of chemical reactions simulating a volcanic eruption! Students will be capti- vated and learn about the concepts of chemiluminescence, decomposition reactions, polymers and catalysts. Demonstration Notes included. Concepts: Chemiluminescence, oxidation–reduction.
Time Required: 25 minutes
Chemicals Provided: Hydrogen peroxide solution, food coloring, polyurethane foam, yeast and light stick chemicals.
Note: A large fiberglass demonstration tray (AP5429) is recommended.
