When you were a child did you ever make scratch art using crayons?
I remember spending so much time colouring a sheet of paper
with so many colours then covering it all in black.
It took a lot of crayons but when it was done it was so exciting to see the
colours show through when you scratched images in the black.
This CD scratch art is the same concept but a lot less work.
I found the idea at wimp.com
First you paint old cds with black paint. The website said
to use acrylic but I used tempera.
Then let the children use toothpicks or skewers to
scratch the paint off.
As they scratch and move the cd, the light will shine on it and they may
see a variety of colours shine through.
