Phosphorescent Powder

Use this glow-in-the-dark powder by mixing it with a medium to illuminate everything in your life.

Brain Spice says: when I was a kid, I mixed phosphorescent powder with some of my mum's clear nail polish - with permission - to make glow-in-the-dark paint!  I painted my plastic model skeleton, and he glowed every night after that.  You can also mix the powder with putties or slimes - whatever you can think of.
