I replaced my car’s emergency lightsticks with these. Pretty cheap in comparison, and with that price I can afford to swap out yearly. The original (came with the car) was 3 years old, and barely lit when I snap it.
now that makes me curious if glowsticks do die of age like batteries or they die due to some other factors
if storebought glowsticks are already dead by age… hmmmmm
Agreed ordered a bunch from Amazon this summer for the kids!
owow dat video
why not just put in boiling water lol
Microwaving a sealed container of liquid then waving it in front of your face until it explodes, pretty sure Jack isn’t the smart one in the family. Dad wasn’t much help either.
KuoH
Dad is more worried about the son’s “beautiful shirt” than his eyes. Besides the chemicals there is also broken glass. When you snap glow sticks its a thin inner glass vial that your breaking.
apparently beautiful shirt costs more than raising his child lol
btw any of you used mini glowsticks?
I saw this while googling and they seemed like temporary trit vials lol
I believe I saw some on my nearby store but never bought it to try. (never wanted red sticks as they usually sucked)
so many party based glowsticks of so many kind
Gotta try em all one day lol :party:
I can not help the notion that if you use light indirectly to repeatedly charge a phosfor to make it glow, you would have got more light (less conversion loss) if you just let an efficient (if you like the GITD colour, use a green or lime one ;-) ) led do the lightmaking work continuously....
possibly
So cute!! 
How long do they last?
I have to wonder about the difference between GITD pigments, and phosphor used in normal leds, ive been thinking about some remote phosphor/GITD using a uv led instead of the royal blue that regular leds use
My daughter likes the one that are sold as bracelets and they seem to last a ton longer than I remember. most are dead after 9ish hours, but some are moon light bright for a day or two afterwards. I can not help to think that temperature they are stored at might have something to do with how long they are good for. I know that being exposed to light causes them to break down.
gonna buy some mini sticks today
will see how they do when night falls~
I guess glowsticks are preserved best on cold areas~
It’s never below 25 degree celcius in Malaysia. Always warm. (air coolers are switched off in stores at night anyway)
Glowsticks are always dead or poor in quality here until this shop brings in fresh stock with manufacture date printed on it 
:heart_eyes: 
I never saw mini glow sticks!! They’re so cute!!!
Then put them in the fridge?
I remember they say putting the glow sticks in fridge helps prolong the lifetime. Is this claim right or wrong？
sadly mini glowsticks ran out of stock…
wow…
I’d always thought glowsticks were out of date in my area
everyone’s switching to freebie led glowsticks here
I don’t know about prolonging lifetime in fridge. Nevertheless I put them inside the fridge to prevent tropical heat >.<
I know that once activated and glowing, putting it in fridge drops the brightness but prolongs runtime
(it’s the other way around when you heat the sticks it shortens life but gets brighter… hence the microwave glowstick explosion vid lol)
I’ve tried boiling glowsticks chemical and it get real bright but once it starts to bubble and boil, the chemicals change and stopped glowing “immediately”
I’ve also poured glowstick chemicals on dry ice and it froze… but didn’t stop glowing
I should consider posting a video one day to try things out mm (I guess i’m too lazy to do so)
NEVER count on a glow stick working for you in an emergency situation. They do have a finite shelf life and there is no way to test them before you need them. There was a story linked to on this forum about some cave explorers that determined that over half of their glow sticks (even those from reputable makers) failed to work properly or at all.
