Luminescent chemical reaction
Materials
luminol, hydrogen peroxide, glowin, coloring substances (eosin, fluorescein, methylene blue), potassium ferricyanide.
Experiment
I have 5ml of potassium ferricyanide and 4 drops of hydrogen peroxide in each of the 4 test tubes, and i add in the second tube two drops of eosin, in the third
tube two drops of fluorescein and in the last two drops of methylene blue, for finish i add luminol in all of them. This reaction create a glowing light in the tube.
How does it work ?
The chemical reaction between hydrogen peroxide and luminol make a source of light, this light emission lasts approximatly 5 sec, but when the chemical reaction is
over, the production of light ends.
Conclusion
This chemical reaction produes its own light as a consequence it's a primary light source
