Using this purple fluorescent pigment is easy. First, add a little water to it. Then, you can paint it on any surface you like to create a cool look under black light. But don't use it on your bare skin as body paint and never eat it. After you're done using it, the paint will dry quickly at room temperature. To clean it up, just use soap and water. You can also get really creative and mix it into things like resin, slime, waxes, or hand - formable plastic. Have fun with your DIY projects!
