Finding plain old glow in the dark paint can be tricky these days. All of these paints do glow in the dark: that’s for sure! But some need a little charging. Boost your blacklight paints by shining a UV light over them for thirty seconds to a minute before turning out the lights. This pumps up the glow and the colors! Many of these sets include a small UV flashlight just for this purpose. Make sure you read the full details and instructions of each product carefully to distinguish which of the paints are stand-alone glow in the dark formulas, and which need a UV/blacklight charge to get the party started!
