Glow Sticks And Camping Memories
- Melissa and Jam reminisce about glow sticks as camping staples and Halloween items.
- Jam shares that glow sticks helped his family find him during camping trips.
How Glow Sticks Make Light
- Glow sticks glow because a fluorescent dye absorbs energy and emits it as visible light.
- The dye itself enables visible emission while a separate chemical reaction supplies the energy.
Dye Structure Determines Color
- Fluorescent dyes have conjugated systems that let electrons be excited and then release energy as photons.
- Those photons have specific wavelengths which determine the glow color.
