Art & Crafts
Instead of discarding those old CD's, why not create a piece of art. Add old computer parts to make a more interesting work of art. Use E6000 glue and glue a few pieces at a time. Be patient with this process because it takes time to dry and if you try to glue it all at once, it will fall apart...Trust me!
You can make moveable parts too. Use an old CPU fan that you can spin on your own. Dangle a CD by using beading thread or fishing line.
Fun project....just be patient with the dry time!
