I learned about this activity at a library conference. At the time, the presenter assured us that it was a hit with teens. So, I thought I’d give it a whirl. I coated the shiny side of each CD with two coats of black acrylic paint, and I scratched it with a screw and a needle. When the teens did the project, they seemed to really enjoy it, although it took less time than expected. I let them paint on discarded book boards, which is my backup painting project if things take less time than anticipated.
