Glow in the dark
Illuminating material that glows green in the dark.
Yes. Put Glow in the Dark stickers under direct light, preferably strong UV light, and they charge again. You can recharge them as many times as you like.
Glow in the Dark stickers charge every time they're exposed to light. When the glow has faded, place them under a light source again.
How to get the best glow
Use direct light, preferably strong UV light or direct sunlight.
The longer they charge, the longer and brighter they glow when the lights go out.
Weaker indoor light also charges them, but the glow will be shorter.
Reusable
You can recharge them over and over without losing performance. That makes them useful for things like safety signs and decoration that need to glow again every night. See where people use glow in the dark stickers.
