Because the ceiling will fade away in the dark anyway. These stars have a unique white backing so you can use them on any coloured ceiling, and they will still glow brightly. How do you charge them? Leave the bedroom lights on for 10 minutes before bedtime. Energy efficient CFL lightbulbs are awesome for this!

Glow in the dark luminance fades after time. Typically, the light released will be brighter immediately after charge and for the first half hour as the atoms are excited and will begin to fade gently as the atoms calm down.
How does glow-in-the-dark charge?
In fact, the charging of your glow-in-the-dark paint is done by other types of light. The invisible UV light with lots of energy can charge the special phosphors in your paint and make it glow in your bedroom at night.

Why isn't my glow in the dark paint glowing?
You need to use a bright light not a dim one! Charging is more about light quality and less about the length of time you charge it for. The paint is constantly discharging light even during the day, when you can't see the glow. For this reason charging it up all day isn't going to make it brighter at night.
How long should glow in the dark last?
Unopened glow in the dark paint may last for 3 to 5 years. On a wall, it may radiate luminously for up to 10-years, or even 12 if protected with a clear sealer. Fluorescent paint will glow as long as a black light shines on it, while phosphorescent glows after dark for 3 to 4 hours or more.

How do glow in the dark stars work?
They work through phenomena called phosphorescence and fluorescence. The material absorbs energy (usually in the form of a particular colour light) and then releases it as another colour light.
Can you recharge a glow stick?
When you crack a glow stick two chemicals are mixed together to produce light. There's no way to reverse the chemical reaction, so you can't recharge the glow in your glow stick.
Can you reuse a glow stick?
A glowstick cannot be turned off or reused once activated. Once you start the chemical reaction it can only be slowed be placing in extreme cold but will not stop entirely. A glowstick will glow until the chemical reaction is complete.
Does putting glow sticks in the freezer work?
Temperature directly affects glow chemical products, whatever form they are in. The reason an activated glow stick lasts longer in colder temperatures is because the colder temperatures slow down the chemical reaction. By placing a glow stick in the freezer you freeze the chemicals, slowing the reaction right down.
What is glow in the dark?
Glow in the dark plastic and stickers contain a phosphorescent chemical. Phosphorescent chemicals absorb light energy (they become excited) when you charge them by placing them in bright light. They then slowly release the light energy that they absorbed over an extended period of time (they glow).
What are the different types of glow in the dark?
Hi, . . . There are 4 types of glow in the dark things. . . First is glass impregnated material, actually does not self glow, but appears to do, with just a tiny little bit of light on it, that can last for ever. . . Then there is Flourescent materials, that absorb light and release that light later, in the dark, these eventually fade away from working. . . Then there are Phosphorescent materials, which are a chemical action, they will fade when their chemicals are exhausted, insects and some sea creatures do this. . . . Then there are Luminous materials, probably under a number of different n
What is the energy for the emitted light?
They glow without previous light exposure: the energy for the emitted light comes from a radioactive ingredient.
Why was radium used in watches?
Originally, radium was used as an energy source . This practice was later discontinued because of its health hazard. Those who suffered the most were the workers who painted the radioactive dye on the watches.
