Always trying experiments. Here, I wondered if RIT color brightener would glow under black light (I had a blacklight). I figured since it’s designed to ‘catch’ the ultraviolet spectrum to make clothes appear brighter, if I put it on my face (which had no beard at the time), my face would glow too. And… it did.
[also, I figured since it’s safe for clothes, which go on your skin, how harmful could it be ON my skin for the two minutes it took to do this? I tested it out on the back of my neck, didn’t get a reaction, and then put it on my face and took the picture]
