2. There is two chemicals in a glow stick, hydrogen peroxide, and diphenyl oxalate, plus a fluorescent dye. The chemicals encased in the plastic tube are the dye and the phenyl oxalate compound, while hydrogen peroxide sits in the glass vial.

3. When the vial is broken, the chemicals mix and a reaction takes place
When the vial is broken, the chemicals mix and a reaction takes place. The phenol oxalate becomes oxidized, breaking up into two molecules of phenol and one of a peroxyacid ester.

5. The peroxyacid decomposes quickly into C02 gas, exciting the dye that once relaxed, releases a photon of light.

7. The Dangers of glow stick is in the hydrogen peroxide and phenol (produced by a by-product). Phenol is toxic and can cause irritation when in contact with skin. Other side effects include swelling, burning, and in some extreme cases, nausea and vomiting. It’s advise to prevent ingestion of the substance.
