Chemiluminescence: How Glow Sticks Work -- Bytesize Science

- Listen up all you ravers out there! Our latest episode breaks down the chemistry behind everybody's favorite party favor, the glow stick. Chemiluminescence is at the heart of how glow sticks (as well as fireflies) give off their otherworldly light. When scientists first tried to make their own glowing material in the 1960s, they realized they needed two components. The first is a molecule that lights up when excited, and the second is an energy source to excite the first molecule.
To think of it another way, dancers are needed to "light up" a party and a DJ is needed to kick start the dancing. In a glow stick, the dancer is called oxalate ester and the DJ is hydrogen peroxide. But that's not all the chemistry involved -- every unique glow stick color requires a different glowing molecule.

Great Video Thanks! Helped me a lot understand glow sticks for my school science project :)
thanks! this helped me study for my exam
Not a bad video, but I noticed an error right away: Fireflies glow because of BIOluminescence, not CHEMIluminescence, like glow sticks do.
The bio part just signifies that the light is produced from a living organism but that doesnt mean the process happens in a different way, its still pretty much chemically produced light :)
Yeah that's true, fireflies glow because of a chemical process. However, it differs from a glow stick. Hydrogen Peroxide is mixed diphenyl oxalate and a fluorophore dye in a glow stick. According to Google, a firefly's glow is because:
"When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced."
I didn't know that until I checked, but I'm glad I did! My genetically altered glow-in-the-dark hounds of Baskerville will be a big hit on Halloween! Muahahahaha! ;)
Bioluminesens are part of chemiluminesens
It's more complicated than that. Both bioluminescence and chemiluminescence manufacture light through chemical reactions, but the reactions use different chemicals and different processes. "Glow stick juice" is not comparable to firefly glow, and vice-versa.
Saying bioluminescence is part of chemiluminescence is like saying photosynthesis is a part of solar cells. :/
+Paul Kepshire i'd say bioluminescence IS a part of chemiluminescene, because it's a chemical reaction , what you do in the lab is simply a simple version without enzymes
