A project for all those scratched CDs

Everything needed for this project you should have in your home already.

What? You don’t have a ton of useless CDs in your house? My younger children are brutal with them.

But you can also buy a pack of cheap CDs to do this project. It would be great for a large group, or a rainy day playdate. We did it with our homeschool group.

Older kids could do it completely on their own, the younger ages needed varying degrees of help, but what is great about a project like this is that children of all ages can play with it when it is completed.

Materials Needed
:

CDs
toilet paper, paper towel, or similar tube (tin foil is nice and sturdy) –you will want to cut it to about 2/3 toilet paper roll length
thick elastic band longer than the tube
duct tape
paper clip
washer
pencil

Step 1:

Securely tape the tube to your CDs. Make sure the tape doesn’t hang over the edge of the CDs.

Step 2:

And that the tube is centered on both CDs.

    Wait, I’m confused. How does it go? I’m not very mechanically inclined.

    I love how well you give instructions. Step by step with great pictures.

    That looks like fun - we’ll put that on our list for our next rainy day :)

    Hey, another thing to do with scratched CD’s is put them in the microwave for a few seconds. They crackle and spark and generally thrill OLDER kids (and Dad’s) to pieces! (My DH either heard about this from a computer friend of ours or on Myth Busters, so it’s safe, provided that you don’t leave them in there for a long time!)

    That looks like lots of fun. I’ve got tons of AOL cds that have come in the mail that are just taking up space in drawers. This would be a good project to have some of the kids friends do when they come for a visit, especially on rainy days.

    Thanks

    That looks like fun. In our old apartment, I took lots of unneeded CDs (AOL and Earthlink in particular, since they used to send a CD every few days…) and glued them to the ceiling over the bathtub - overlapping to make a demented silver cloud. I wonder what the super thought when he discovered it after we moved out.
