well i just watched something about it but you can watch video its kinda hard explain so here is the link http://video.about.com/chemistry/How-to-Make-Glowing-Water.htm
Neither of these two examples glows of their own right. Both materials reflect light waves that impinge on them. [hint. consider looking at them in a dark room.]These two materials fluoresce due to their component matter fluorescing under ultra violet light. Thus they appear to be reflect more light than is incident.You can easily demonstrate this by putting an UV absorber between the light source and the object.And as to the question - the highlighter is designed to draw attention to the mark - an important property. So we would expect the fluorescence of tonic water to be rather unimportant, whereas it is a design property for the highlighter.
To make water appear to glow, fluorescent highlighter colors like neon yellow, green, or pink work best. The fluorescent dye in these colors emits a bright glow under UV light, creating the effect of glowing water. Remember to use caution and handle highlighter dyes with care when using them for this purpose.
Highlighter ink does not glow in the dark on its own. To make water glow in the dark, you would need to use a fluorescent or phosphorescent pigment designed for that purpose. These pigments are usually powders that need to be mixed with water in specific quantities and then exposed to light to charge up before they will glow in the dark.
The answer is a Black light and Tonic Water. Tonic water contains a chemical called quinine which makes it glow bright blue when the water is exposed to black light.You take a bowl and put water or Tonic water just in case you want to drink it.Then you put highlighter ink in the water then stir the ink in the water. It looks kinda weird, but then you put the black light over it and it GLOWS.
Certain foods that contain fluorescent compounds, such as tonic water, certain types of fish, and some types of cheese, can glow under a black light.
you cut the highlighter in half and take out the felt tip and you put it in a small amount of water. After you put the felt tip in a small ,amount of water you put it under a black light and the water should glow. The best color to use is a yellow highlighter.
use a blue light instead of black light
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.
Glow water glows when exposed to black light or UV light due to the presence of fluorescent compounds in highlighter ink. These compounds absorb the UV light and re-emit it as visible light, creating a glowing effect. When mixed with water, the highlighter ink disperses, allowing the fluorescent particles to illuminate the water under the right lighting conditions. The brightness and color of the glow depend on the type of highlighter used.
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.

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

Put radium in it. Just kidding please don't put radium in it, as it's radioactive and causes cancer. I would suggest putting glow-sticks or anything glow-in-the-dark in it that's safe to put in water. I've also heard of squeezing hi-lighter ink into the water
