Simple House Hold Science Trick: Glowing Water
This one’s really simple, All you need;
 A black light (UV lamp) - You can find this from places like walmart, hardware stores, or you can order it online, here.
Highligher pen
Regular or Tonic Water
Now simply break open the highlighter, remove the felt and soak it in water for a few minutes. If you’re using Tonic water you can skip this step, you will not need the highlighter.
Find a dark room and place the water infront of the UV lamp.
and you’re done, Enjoy!

One more cool tip: If you already have something that glows after being exposed to regular light, try exposing it to a UV/Black light instead. It will be incredibly bright in a matter of seconds!

Wait, what is it about the tonic water that makes it glow like this?

To answer that you have to understand why things glow in the first place;
It’s called the Photoelectric Effect - When an Electro-magnetic wave (photon) passes through a substance it sometimes interacts with the electrons in the atoms. (only interacts with the electron and not the proton because they both have the same field strength yet the electron weighs roughly 2000 times less.) The electron absorbs the energy from the photon and becomes ‘excited,’ jumping up an energy level, then when it falls back down an energy level it releases a new photon in a random direction. so instead of just reflected/refracting light, it actually gives off it’s own light.
This only works when the original photon is of high enough frequency (more energy) which is why the UV torchlight is needed - Ultra Violet light has a higher frequency than visable light.
It also depends on the atom itself, some atoms/molecules have a lower threshold frequency than others (that is why some things don’t glow under UV light) and so there would be something present in the tonic water, in this case Quinine, that makes it glow.
