Glow in the Dark
Illuminating material that glows green in the dark.
Any strong light works. Sunlight and UV light charge glow in the dark stickers the fastest, but indoor lights also work.
To make the stickers glow, expose them to sunlight or a strong artificial light.
UV light and sunlight: the quickest and strongest charge
Indoor lights: also work
Time: a few minutes of light is enough to make them glow
The stickers can be charged again and again. Read more in Is the glow rechargeable? and How long does the glow last?
