The other way the rock can be used is as a placeholder, after finishing a chapter in a book. When you put it on a night stand, it makes a comforting night light that softly fades. Children like this effect, especially if they are afraid of the dark.
Usually a little black light can keep them busy, highlighting the colors on the rock before they doze off to sleep.
Another use for the rock is to have it on your window sill or by the door as a way to remind yourself of something before leaving your home for the day. Some will keep one by their computer to refocus their eyes after viewing the monitor for a while. It just is a colorful item to uplift your spirit every time you view it.
If you can think of other ways to use these rocks, I am always open to hearing your suggestions.
Here is this weeks rock
This is a stacked, heart-shaped rock with a metallic mylar heart adhered in the middle with glow in the dark paint droplets surrounding it.
