Glow Sticks Made From and How Do Glow Sticks Work
In this particular design, the glow stick consists of a glass tube and a plastic tube, each containing one of the two chemical solutions needed to produce the light reaction.
- Glass Tube Component:
- The glass tube holds one of the two chemical solutions required for the glow reaction.
- This solution typically consists of a mixture of diphenyl oxalate and a fluorescent dye, as described earlier.
- The glass tube provides a sturdy and transparent enclosure for the solution.
- Plastic Tube Component:
- The plastic tube holds the other chemical solution needed for the reaction.
- This solution typically comprises hydrogen peroxide, which acts as the activator for the chemical reaction.
Chemical Reaction:
- The glow stick is designed so that the two compartments within the glass and plastic tubes remain separated until activation.
- When activation is desired, the user bends the glow stick, causing the barrier between the two compartments to break.
- Once the barrier is breached, the two chemical solutions mix together.
- The mixing of the two solutions initiates a chemical reaction:
- The hydrogen peroxide reacts with the diphenyl oxalate present in one solution, forming an unstable peroxyacid ester.
- This unstable compound decomposes into phenol and peroxyacid, in turn, exciting the fluorescent dye molecules.
- As the dye molecules return to their ground state, they emit light, resulting in the characteristic glow of the glow stick.
How a Glow Stick Works?
How do glow sticks work? It is a clever invention that is often overlooked by many. Simply snapping them to activate the light may seem mundane, but the science behind how they work is quite intriguing. Made up of specific ingredients that react chemically when combined, glow sticks produce a vibrant and joyful glow that is truly fascinating.
What Makes Glow Sticks Glow?
Different shapes, sizes, and colors of glow sticks contain two essential components: hydrogen peroxide and a phenyl oxalate ester. Inside the glow stick, hydrogen peroxide (H2O2) is sealed in a delicate glass tube, with the phenyl oxalate ester surrounding it. The combination of these two compounds is what creates the glowing effect of classic glow sticks.
Various fluorescent dyes are utilized to create the vibrant array of colors found in glow sticks. Rhodamine B produces a red hue, rubrene yields a yellow shade, diphenylanthracene creates a blue tint, and 9,10-bis(phenylethynyl)anthracene results in a green glow. While the technical names of these dyes may be complex, their impact on the glow stick’s appearance is what truly counts. Further elaboration on this topic will be provided in the following paragraph.
