Q:Is this powder re-chargeable? A: yes, this powder is "charged" with any source of light (sunlight works great) and will glow for 2-24 hours afterwards, depending on the color and charge time. Once they stop glowing, they can always be re-charged, and do it all over again. These powders are rated not to get any dimmer or shorter-lasting for 15 years!

Q: Can I use this to make paint? A: Yes, you can! Unfortunately it is a little difficult, because this powder is fairly heavy, like sand, so you will either need to stir the paint before every use, or use thickeners. I've had best luck with acrylic mediums, preferably as clear as possible, and best results when painted onto a white background.

Q:What color is the sand in the daylight? A:Most are pale off-white, or pale versions of their glow color.
