black light and glow rings
Using black light, the gin
and tonic glows in the dark.

The colors we see are determined by the wave-length of light energy. Unlike some insects, humans can only view the spectrum from red to violet. However, other invisible “colors” exist above and below this spectrum.
The “color” above red is called infra-red and the color below violet is called ultra-violet. Ultraviolet light will cause fluorescent or phosphorescent pigments to fluoresce, emitting visible light. – Glow Inc. Link
The black light experiment happens again at Tanja's annual party with another gin and tonic in January 2010.
Party glow rings.
The glow light is made of
two parts which when mixed together create the chemical reaction which makes them glow.
4 g sodium carbonate
0.2 g luminol
0.5 g ammonium carbonate
0.4 g copper sulfate pentahydrate
approx. 1 litre of distilled water.
50 ml of 3% hydrogen peroxide.
Glow sticks work by a chemical reaction called “chemiluminescence” which causes light
to be generated. (That's a trivia question for some party games!) By breaking up the word "chemiluminescence" into 2 parts, chemi and luminescence we can better under-stand. Luminescence is emission of light not caused by a rise in temperature (the object emitting light stays cold). The light is released by atoms returning from "excited" (charged) state to normal "ground" state. It means, an object which glows, first must absorb energy to get into "excited state." That energy will be released (in form of light) by the object returning to the ground state of energy.
