Glowing powders encased in arcanely-shaped bottles with corks.
These are my actual glow-in-the-dark supplies. They’re powders and sands (on the right).

TheGlowInTheDarkMan.com is my new Zen Cart shopping site. However, I do not take credit cards. If you need to use a credit card, I can post it in my Etsy store and you can then use your CC. So just let me know what you’d like to buy from TheGlowInTheDarkMan.com and I’ll post it there, too….

Thanks for your understanding.

Oh! The reason that I got excited about glow-in-the-dark was because I saw the product specification for products from https://www.glowinc.com. I mean check out the spec on their green V10 here: http://glow.glowinc.com/glow-powder/ultra-green-v10-glow-in-the-dark-powder-55-85-micron/ “For retail products, brightness is essential.  V10 55-85m has a  brightness rating of approximately 33,000 immediately after charge, 945 at 10 minutes, and 126 at 60 minutes.   It continues to be visible by the human eye more than 24 hours after the initial charge.” (Their emphases, but good ones!)

I mean, say what? It glows for > 24 hours?!? And IIRC, your brightness doesn’t need to be anywhere near 100 for it to seem bright. I simply had to try some. And I think they’re right! The good stuff does glow for more than 24 hours! And it is so bright that you can see it glowing with the lights on!
