Glow in the Dark Toys

Glow in the dark toys are like little batteries. They store energy from the sun and then slowly emit it, slowly releasing it. The phosphorescence process is happening in glow-in-the-dark toys. It's sort of like you've pushd the electron up a hill, and then before it can roll back down, it gets caught on some ledge or something,. And it has to hang out there for a while.
