This is a cool experiment for my fourth grader but she also needs to understand why the liquid glows.

Tonic water does not glow when mixed with green highlighter ink because the quinine in tonic water, responsible for fluorescence under UV light, is not reactive to the wavelength of light emitted by the green highlighter ink. The fluorescent properties of quinine are specific to certain wavelengths of UV light, which the green highlighter ink does not produce.
The experiment of glowing water involves adding a small amount of a fluorescent dye to water, causing it to emit light when exposed to certain types of radiation such as ultraviolet light. This phenomenon is due to the absorption of energy by the dye molecules, followed by their emission of light as they return to their ground state.
To make glow in the dark lip gloss, you will need a clear lip gloss base and glow in the dark powder or pigment. Mix the glow in the dark powder or pigment into the clear lip gloss base until well combined. Apply the lip gloss using a lip brush or your fingertip for a fun glowing effect.
Highlighters glow under black light due to the presence of fluorescent dyes, typically compounds like pyranine or rhodamine. These dyes absorb UV light and re-emit it as visible light, creating the glowing effect.
To make glow-in-the-dark icing, use tonic water as a liquid ingredient in your icing recipe. Tonic water contains quinine, which glows under UV light due to fluorescence. Simply substitute the water or other liquid in your recipe with tonic water to create glowing icing that is safe to eat.
