Blue UV Black Light Powder

This comes in a zip lock bag, rather than the bottle shown. The power is a greeny-yellow rather than the white shown. Under UV the powder glows greeny-yellow rather than the blue shown. The fun really starts when mixed with a lacquer and when it is applied to the wall. It is almost invisible under normal light, but really stands out under UV light, the effect is quiet spectacular. It also alters it's colour depending on what colour it is painted on, I haven't figured out how to get blue yet, but it's been fun trying to figure out what combinations work together. I'm still trying to figure out how best to use this in my mural, but it's a definite addition.
