Ever wonder how that two part solution works or if you can make your own? The answers are in here.

Step 1: You will need....

Chemicals Required:
Sodium Hydroxide (lye)You can use "Red Devil" drain cleaner or buy it on eBay.

Luminol, also available on eBay.

Hydrogen Peroxide (3% drugstore variety)

Sodium Ferrocyanide, also known as tetrasodium hexacyanoferrate or sodium hexacyanoferrate (II), is
(of course) also available on eBay.

Container to mix in. DO NOT USE METAL!!! They may react with the sodium hydroxide. Especially aluminium.
Generally this in non toxic, but that isn't an excuse for abuse!
Where can i find hidrogen peroxide???
<p>It is used for cleaning cuts.</p>
almost any store except clothing and toy stores has it drug stores have to have it. it always comes in a dark bottle that blocks light cause it is light sensitive
what happens if you expose it to light?
It breaks down into water
peroxide breaks down when exposed to light and it will become ineffective and not capable of doing its job
Any Pharmacy/Chemist/Druggest/Apothacary or grocery store. You will find it in the first aid section.
PLEASE HELP! Can someone tell me whats the purpose of each chemical. Im doing this for a chemistry experiment. Any technical info would be great, thanks.
do you know how to make different colors? food dye maybe?
You need a fluorescent dye to change the colour - you can buy fluorescene cheaply (for yellow) or can probably use the dye from a fluorescent highlighter pen.
Also, if you have any old glow-sticks, the glow may be exhausted but you could probably re-use the solution to colour your luminol reaction.
well, maybe it would be a better idea to think in terms of fireworks? Phosphorus and such would be more likely
do you need the Sodium Ferrocyanide<br>
It's the complexed metal that you need - in this case iron. <br> <br>You don't specifically need Ferrocyanide - they use luminol as a test for the iron in blood (if you ever watch CSI). Something like &quot;sequestered iron&quot; that you buy for plants would almost certainly work equally well, but you do need something (assuming you don't want to open an artery).
With this recipe, YES. <br> <br>D'oh!
Duh, where can I get sum water? You mean the stuff from the toilet? Huh, huh, huh. I betcha Mine will glow if I set a match to it...
Would it be weird to do this as a high school chem. experiment? We get to choose our last one and i'm looking for something cool...
This would be a good, safe experiment for your class. the only protective equipment required for a class room setting would be goggles, gloves and an apron. easy to do and neat to look at too. much safer than my thermite.
Thank you! :)
How do we get the different colours do you know? Can we just add food colouring?
But to answer your question, one way would be to use a lighting gel wrapped around your container, or shoved inside the container, to change the spectrum of visible light.
That is like asking if you can change a blue LED to orange by shoving it into food coloring...... think about that?!
I never did pursue it beyond "ooooo neat it glows."
lol. I know how that is. Always fun to marvel at something so simple yet so complicated.
so cool! 2 questions-- how long does that last for, and chemically what is it that makes that glow if you know? so crazy nicely done <sup>_</sup><br/>
The chemical that makes it glow is the luminal
things that "glow" are giving off light because electrons in their atoms are in an energized or excited state. when an electron descends from a high-energy orbital to a lower energy orbital, a photon is given off (light). think of it like floors in a building. the chemical reaction here is energizing the electrons, so it's like taking the elevator up a few stories in a building. electrons naturally want to be in the lower energy states, so they give off energy in the form of light to get back down... when electrons descend slowly (picture taking the stairs instead of the elevator) it gives off a very pleasant glow. this is the same reason that really hot metals glow (burner on your stove) and glow-in-the-dark materials glow. when you "charge up" something that's glow-in-the-dark, you're exciting those electrons and moving them up to higher floors in the building... when you turn out the lights, they hit the stairs and come back down to the ground. in this reaction, energy is being given off in the interaction of the two chemicals, exciting the electrons and giving off light until the reaction has spent all of the original chemicals. my first post on instructables!
It usually lasts for about eight hours, depending on the temperature. As for how it works, I haven't a clue really.
I did a little searching and found this experiment: <br>http://www.chem.leeds.ac.uk/delights/texts/Demonstration_23.htm<br><br>Apparently this experiment uses Potassium hexacyanoferrate(III) which is very toxic, but produces GREEN. Make sure you review the safety information on the linked page.
mnyessssss, i can see giant vats of glowing yellow fluid already. excellent
blue actually (see step four), but yeah
oh btw, any idea is it possible to reverse the reaction? separate it back out somehow? if not then im just hoping i can buy the ingredients cheaply :P oh also, an important point, how do you safely dispose of this stuff? cause things like Luminol and Sodium Ferrocyanide dont sound very healthy and im not sure if it would be a good idea to just sink it.
Hi! I really love this, but do you know if the luminol can be bought in a store? And do you know whether you can put this on clothes and safely be able to wash it out too? If so i might have the watergun idea at my birthday :)
Pedal extenders are an ingenious <a href="http://www.cheap-uggs-boots.com/ugg-nightfall/" rel="nofollow"><strong>UGG Nightfall</strong></a> addition to the piano. At first sight, they look like a footstool and can serve the purpose of giving a child a place for the feet so they do not dangle freely, but <a href="http://www.cheap-uggs-boots.com/ugg-nightfall/" rel="nofollow"><strong>UGG Nightfall Boots</strong></a> they also have piano pedals. Piano pedals sit on the top, and underneath are posts that sit on the pedals of the piano, so that when <a href="http://www.cheap-uggs-boots.com/ugg-nightfall/" rel="nofollow"><strong>nightfall uggs</strong></a> the child pushed the pedal on the footstool, the piano pedals are pushed by the extenders. With an adjustable piano bench, the child can be at the <a href="http://www.cheap-uggs-boots.com/ugg-nightfall/" rel="nofollow"><strong>ugg 5359</strong></a> correct height to play the piano comfortably.As a beautiful piece of furniture a sheet music cabinet can take place with other pieces of furniture. But its real purpose is to keep the many pieces of music organized and out of sight. Most piano benches <a href="http://www.cheap-uggs-boots.com/ugg-nightfall/" rel="nofollow"><strong>ugg 5359</strong></a> can hold music, but this storage space is limited.
This is really cool, but whenever I see the word, CYANIDE, I get a little jumpy. Surely there is a way to do this using safe chemicals. Even though your mixtures seem pretty weak, are there any alternatives?
it is safe.if you want know more about the glow products,please contace me <a href="mailto:per@hzruiyuan.com" rel="nofollow">per@hzruiyuan.com</a>&nbsp; MSN:zixueshan@hotmail.com
Sodium ferrocyanide is also known as yellow prussiate of soda. It is used in table salt as an anti-caking agent. If you read the MSDS, it states that it is not toxic, yet I would still worry about drinking the stuff, especially when you're using sodium hydroxide. People also need to be careful with non-solution sodium hydroxide. It is extremely exothermic when mixed with water, although the quantity used in this is not enough to worry about.
"When they see us coming, the birdies all try and hide, but they still go for peanuts when coated with cyanide!"
Ahh yes, poisoning pigeons in the park. One of my favorites from the Dr. Demento days. And thanks iman for straightening that for dchall8.
ya dont need to be too jumpy :)<br/><a rel="nofollow" href="http://en.wikipedia.org/wiki/Sodium_ferrocyanide">http://en.wikipedia.org/wiki/Sodium_ferrocyanide</a><br/>
I wonder if Prussian Blue (aka Laundry Bluing) would work in place of sodium ferrocyanide.
&nbsp;It's the same thing, you're set.
ok 1st of all the pic at the end is very misleading. You will not get that kind of glow with this fluid. This formula works great but only lasts a few seconds depending on your H2O2 concentration. After mixing the 2 formulas I have to let mine sit overnite to make it work right, not sure why, maybe temperature or I can use it right away if heated. The glow is a bright blue and is really cool for a science experiment but again its really fast.<br />
I just saw a video posted on another site of someone making a glowing substance with mountain dew, peroxide, and baking soda. Has anyone tried this before?
I tried the Mt. Dew thing was bogus don't bother.
Those videos are bogus. Some wiseinhimmer decided to make one as a spoof on real science.<br /> Probably didn't do well in the subject at school and decided to &quot;get revenge&quot; by making the fake video. Then, of course, others did the same thing.<br />
buy cool aid mix and try to color it be carefull it stains clothes (tried to make fake blood with it)
isn't this stuff toxic? lol very cool though ;')
