 | Fluorescence is caused when the electrons are raised to an unstable excited state. The black light raises the electrons to this state, as it is UV light, which has a higher energy than white light. When the electron moves back into the ground state, it emits a photon of energy, which is what you are seeing.-Draevyn |
 | You should never drink anything out of the lab, but in this case it safe to do. Tonic water naturally fluoresces due to the presence of quinine. And it is TASTY!-Micheal |
