Glowier than a glowy thing!
The glow this stuff gives off is AMAZING! it doesn't take much 'charging' and it glows for a decent amount of time and with a good, bright light. I was really impressed!
Also, when the site says you don't need much of a product to get the effect you're going for, it really means it! Use sparingly unless you want head-to-toe glow-in-the-dark alien children (honestly, it was hilarious).
I used the powder in soap jellies (shower gel, gelatin, colour)
