How to Make a permanent, reusable glow stick


Make a reusable glow stick, glow-in-the-dark-style! Imagine, you'll never have to buy one of those ChemLite's again, because you can reuse this homemade glow stick over and over again. This video tutorial will show you how to make a permanent, reusable glow stick. The materials in this experiment are simple: epoxy resin, straw, and some phosphor powder.
C For Chemistry delves into the chemistry of science experiments. This chemist knows what he's talking about. These chemistry experiments are not only fun, but very educational for all of those interested in scientific chemical reactions and properties.
HOW TO:
1. Ready the epoxy resin.
2. Copper doped zinc sulfide is added to syringe.
3. Add an equal amount of epoxy resin to the syringe.
4. Stir with a glass rod.
5. Inject mixture into tube (straw).
6. Leave syringe and tube undisturbed until completely hardened.
CHEMISTRY OF IT:
Phosphor powder carries property of phosphorescence, which is a specific type of photoluminescence related to fluorescence. Don't confuse this with chemiluminescence used in commercial glow stick, which depends on energy of chemical reactions.
