Put my equipment on- some of the chemicals are corrosive so if you are planning to try this experiment at home, be sure to put your gloves on.
I first prepared two stocks solutions, one containing Luminal C8H7N3O2, the light molecule, and one containing Potassium Ferricyanide K3[Fe(CN)6].
After I had this stock solutions I made 2 diluted solutions. I started with the Luminol by adding 0.5g NaOH and 0.1 g of Luminol, and dissolved the
mix in 50ml of H2O. I called this stock solution A. I got the second stock solution by dissolving 0.3g of K3[Fe(CN)6] in 97ml of H2O, and called this
stock B. I then made diluted solution from my stocks, first took 5ml of the Luminol solution from the stock A, and diluted in 35ml H2O, then did the
same thing with the Potassium Ferricyanide, but in this one added 0.5 ml extra of hydrogen peroxide with 30% concentration. Then turned the lights off
and got the light from my chemical reaction while I mixed the solutions. This kind of light is used by detectives to trace blood.

The luminol experiment! Very fun! I use it when I do demonstrations for elemnentry schools! Really gets the kids attention.

It would be more interesting to see a picture or 2 and a video rather than just seeing a recipe.
Be sure to talk about the actual reaction if you are going to do a video. Most amateur's chemist's videos don't talk about it, don't show any
equation, or don't properly measure things.
