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.

Is Tonic water acidic or alkaline?
The PH level of tap water can change depending on where you are. Due to the fact that water treatment plants use diffrent chemicals which may alter the pH level of 7 that pure distiled water would have (:
What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".

How do you prepare fluorescent dye?
There are a couple of ways you get science projects to glow in the dark. You can use glow-in-the-dark paint, which is phosphorescent and glows anywhere from a few minutes to a few hours. Glowing paint or powder tends not to be very soluble, so it is good for some projects and not others. Tonic water glows very brightly when exposed to black light and is great for edible projects. Fluorescent dye is another option for a bright effect under a black light. You can extract non-toxic fluorescent dye from a highlighter pen to make glowing water:Use a knife to (carefully) cut a highlighter pen in half. It's a pretty simple steak knife and cutting board procedure.Pull out the ink-soaked felt that is inside the pen.Soak the felt in a small quantity of water. I made avideo of what to expect.Once you have the dye you can add it to more water to make glowing fountains, grow certain types of glowing crystals, make glowing bubbles, and use it for many other water-based projects.
How do you keep away mosqعuito?
You could pour a little bit of tonic water into your morning drink every day. Because female mosquitoes prefer sweet blood, they will be more attracted to you not those who have sour. Tonic water makes your blood more sour, so then it would repel mosquitoes. But remember that you have to do it every day or the tonic wont work. It might take a few hours before it starts to work though.
Is too much tonic water bad for you?
There is a chance that even small amounts of quinine, the bittering agent in tonic water, can cause side effects from diarrhea, to blindness, and in rare cases--pulmonary edema, possibly resulting in death. While casual consumption of tonic water seldom results in more than the mildest of side effects, prolonged and heavy consumption can build to intolerable levels resulting in renal failure.It should be noted that levels of quinine in tonic water are minute as compared to therapeutic doses and evidence that drinking tonic water for cramps or other preventative measures cannot be confirmed.For further information explore Quinine Toxicity.
Is water an isotonic solution or hypo tonic solution?
Distilled water is hypotonic to undistilled water. Undistilled water is hypertonic to distilled water. Undistilled water contains chemicals, if you live in the city, and minerals and nutrients. These would be considered impurities to the pure H2O, or solutes dissolved in the water. Because the undistilled water has substances in it that the distilled water does not, it is hyper-(above)-tonic. The deionized water is hypo-(below)-tonic to the dirty water.
