Luminescent Chemical Reactions
-Glowing, coloring substances (Eosin, Fluorescein,methylene blue)
We mix potassium ferricianide and luminol in the first tube ; in the seconde tube we mix potassium ferricianide, luminol and eosin ;
we mix, in the third tube, potassium ferricianide, luminol and fluorescein ; and for finish, we mix potassium ferricianide, luminol and methylene blue in the last tube.
How does it work ?
When the luminol meets the other substance(s) we see an "explosion" of light.
There are primary sources of light because they produce their own light.
