Picture of Make your glow sticks SUPER Bright
In order to make your glow sticks super bright, just crack them, put them in a microwave for 10 seconds. WARNING: Glow sticks can pop in the microwave if left in to long.

I bought these glow sticks, 1000 for $40 on e-bay, some worked great, but others were kinda dim, a search of solutions turned up this. The life of the glow stick is shortened slightly (12 hours instead of 24) but is much brighter and more useful.

Just take dimming glow sticks and place them in the microwave for 10 seconds...
Microwaves excite the hydrogen peroxide in the glow sticks and make the glow sticks react faster (brighter). They will still last for hours though when they start to die, they die for good.

Oh wow! It works. I nuked mine in the microwave for 30 seconds. After I shook it, it got so bright the entire room turned yellow. I had a yellow glow stick. Darn thing lasted 3 weeks. Thanks guys the tip!

Irresponsible instructables post that should be taken down. This video shows why this is a bad idea.

DON'T DO IT FOR MORE THAN ZERO SECONDS. This article should be deleted before someone gets seriously hurt. "Oops, I'm blind and don't have a face anymore, but my glow stick was SUPER bright!"

Don't do it period.

5 secs is more than enough. 10 secs is on the "run it's gonna blow" side of it

Be Very Careful Microwaving Glow Sticks People!

and don't throw away your old glow sticks. they can be used as party decorations with blacklights. when a blacklight hits dead glow sticks, they look live again

Cool. Never knew it.
Put them over a radiator thats on or in some hot water, and to make them last longer but with the expense of dimmer sticks, put them in cold water or in a cold fridge :)

cut down the life heaps tho
it increases the speed of the reaction
Yeah the heat will definitely speed up the reaction, but what happens when they cool back down to ambient? Are they just as bright as when hot? It'd be interesting to find out.
You are right about it speeding up the reation. The life of the sticks will drop quickly (that's why refrigerated sticks lasts for days), I would assume that it would slow down again or run out suddenly
They Glow GREAT for a couple hours, then go to normal, when they die though, it happens rather suddenly.
If you want glow long time .please scan that
send email to
yup, it's just a normal chemical reaction happening inside (although one that excites colored dye in the process) so it'll slow down as it cools. be cool to take the stuff out and heat it on a bunsen burner or something, and see how bright you could get it.

Why would you use a glow stick if you are near to a microwave that can be powered anyway?
because you cant run around in the dark with a microwave that turns into a cool colored stick when you crack it, BECAUSE you would have broken the microwave. That's why

you guys said stick
yes these people apparently microwave their sticks, as some sort of performance enhancer?
DAMN!! i gotta try that then,
I have microwaved a hotdog before and would like nothing better than have my stick crack/explode like that lol
oh, that sounds AMAZING

I heard that freezing them works also.
heat = faster reaction
cold = slower reaction
no, freezing them makes them last longer by slowing the reaction.
hey,does this work with those glow in the dark beads?!
lol, glow sticks use chemicals, beads don't

Cool, mine exploded and now my microwave glows in the dark!
yes lol is correct
well what every youdo just dont stick markers in a microwave!
why not stick markers in the microwave ???????????????????
they will explode so dont do it in a brand new microwave.
if you stick an egg in the microwave it turns purple :P
for how long?
