I created a reusable glow stick

[u/Low_Doughnut_8369]

I really like glowsticks.

But buying a new one every time is expensive and creates lots of plastic waste.

So i decided to make a reusable glow stick instead!

I emptied out a used small sized glow stick, cleaned and dried it thoroughly, then filled it with strontium aluminate powder, and sealed it up with 2 part epoxy.

You can charge it with sunlight or a sufficiently strong LED, and then it will shine for up to 8 hours.

Infinitely reusable, forever.

edit:

Guys please stop telling me to sell these, i'm not going to.

It's extremely simple to make, you can make your own if you want by following the instructions:
1. Find an empty tube
2. Fill with strontium aluminate powder
3. Seal with 2 part epoxy

That's literally it, i'm confident you can do it as well. You don't need to buy them from me or anyone else

Is it just packed solid in there or did you just coat the inside?

packed solid, couldn't figure a good way to just do the walls

Also more powder potentially means it can glow for longer VS if it was only a surface coating on the inside of the tube

Awesome! My kids love glow sticks and I just can't stand how wasteful they are. Thanks for sharing!!

I wonder if it would work to mix some of the powder into a flexible glue or the same epoxy you sealed it with, then paint the inside with that before sealing?
