DECORATE YOUR CEILING OR WALL WITH THESE GLOW IN THE DARK STARS & MOON (13-PCS)
Fall asleep while watching the moonlight!
This set consists of 12 glow in the dark stars in different sizes and 1 big moon. The stars charge light up during the day and shine off green light in the dark.
Glow-in-the-dark stars are ideal for children that are scared the dark. This way, there is no need for a night light when the child goes to bed. Due to the asterisks there is still light. The advantage is that the light does not have to be turned off. The asterisks will of course give less light.
For an extra good effect, shine with a bright lamp on the stickers before turning the light off.
Size: varying from 4.5 cm to 11 cm and the moon is almost 30 cm tall
Including self-adhesive stickers
PROCESS GLOW IN THE DARK
Another name for glow in the dark is phosphorescence or fluorescence. It simply says that the product absorbs the light and releases it in the dark. This can be done with phosphorus, but also with newer chemical compounds. It must be very dark to get a good effect. If it is not dark enough, the glow in the dark will not light up. The glow time depends on the workable material in the material and the amount of light stored by the product. This may vary from a few minutes to a few hours.
