I have a few old ones that I'd like to recycle, but don't have a good idea for a simple project. And by simple I mean really simple cause I may be a lot of things but handy and crafty are not among them. I was thinking about decorating the scratched ones (or those where color is chipping off) with glitter gel, or glitter glue, but never tried using it. Is the color on those transparent (like some gel) or solid? Is there something other than bleach that can be used for taking off the silver layer from inside the ball? How to easily paint the non-silvered ones i.e. those made of translucent glass? Thnx!
