And by that i mean, put all the ingredients together and made your own custom made glow jar / whatever, i wondered if a jam jar full would be enough to make the entire room glow...

(I found the ingredients on a website)

Glow stick formula

1. 50 grams of sugar
2. 25 mls of 50wt% NaOH
3. 5 mls of Isopropyl Alcohol

Slowly stir sugar into NaOH, Green color will develop with no glowing characteristics,
Add IPA only when you want the mixture to glow.

NaOh is sodium-hydroxide, you get it in a jar:)

25 mls of 50wt% NaOH (below is 500grams)

3. 5 mls of Isopropyl Alcohol (below is 125ml)

IF this works, it'll be interesting to see how powerful, how long it lasts for or if it's even worth doing it again

Just buy a few pounds of glow powder and load it in a jar :D

The initial brightness would prob light up a small room faintly then dim to the surrounding areas. Another problem is the powder towards the centre of the jar won't get much light, so you don't really need a full jar of powder.

Maybe put another smaller, closed empty jar inside the big jar to take up space so that the powder only lines the walls of the big jar.

I dont think that formula is correct. Sodium hydroxide (or some less noxious base is generally used) is necessary to dissolve the oxalate phenol esters but there are a couple of things not listed there, like the actual chemical that gives off the light when mixed with hydrogen peroxide...

You can actually buy "luminol" which is the phenol stuff from some police supply places I think, as it's used to make certain other chemicals fluoresce. Or perhaps just regular lab supply.

The wikipedia articles on "cylume" are pretty good I think here:

http://en.wikipedia.org/wiki/Bis(2,4,5-trichlorophenyl-6-carbopentoxyphenyl)oxalate

and just the generic glowstick article links to this great video of a guy making his own for wired's "hack" segment:

LED Candle,

The easiest way to do that is to put glow paint in a jar and rotate it to coat the inside, then dump the excess. To maximize brightness, you could then follow up with repeating the proceedure with bright white paint.

Our customers do this with alcohol bottles for bars.

A similar effect is to only paint the bottom of the bottle and let the glow project up through the glass.

go buy yourself a glowbrick and be done with it :)

B@rt has one, I think he did a review also

I've made "glowstick formula" before; the recipe cited in the OP is certainly off. I'll edit this post in a little while to give more detail, but the glowstick chemistry actually uses H2O2 (hydrogen peroxide) to oxidize a rather specific fuel (the oxalyl/phthalyl ester mentioned above) which gives rise to a high-energy intermediate. This intermediate decays exothermically and spontaneously, and when you have fluorescent dye in solution some of the decaying C2O4 intermediate molecules couple energy into the fluorescent dye, exciting it and setting the stage for fluorescent relaxation.

The reaction requires fuel, concentrated H2O2 (I used 30%), an appropriate dye, and a solvent that works well. Diols/glycols seem to be good solvents, though the cyalume chemistry uses something quite different that I never got to work very well. The wikipedia article posted above is quite good. If I replicate the chemistry again at any time I'll post some pics.
