sticky and can be painted onto almost anything, including wood, fabrics, glass, and metal.

Step 1: How it Works
The sellers of the newer phosphorescent powders are cagey and do not want to reveal what exactly is in their glow powders. It does appear that the best ones available today are Strontium Aluminate that is activated by Europium,
In any case, they all work by absorbing visible or Ultraviolet light which charges the photophosphorescent molecules by absorbing the photons and moving the electrons to a higher orbit. As they slowly move back to their original orbits, visible light is given off. The best available phosphorescent powders once charged, will give off light all night long and will still be visibly glowing in the dark twelve hours later.
Some of the colors are quite bright and can be used to make a short lived flashlight that is bright enough to read by.
Ooglo is Oogoo that is thinned to a paint like consistency and mixed with various colors of phosphorescent or fluorescent powder.
