If you drill a hole in the cd air and or water will get to the aluminum coating and oxidize to a non reflective frosty look. A light coating of glue or clear fingernail polish can seal a small opening. Have to be very carefl cutting them or the foil will rip off. On some cd's the foil isnt fused to the plastic except around the perimeter. A good sun catcher can be made by tying a string through the hole and around the cd. Give yourself 3 or 4 inches of slack then tie on another cd. Keep on going to make as long a string as you like. Put a weight on the end of the cd chain and hang it from a high limb where the morning and afternoon sun can hit it. Pretty interesting light show. Cats and dogs are often freaked by the display, but birds just kept right on like nothing was new. If you would like a little neater chain, use silicon glue to put the cds together with a 10 of 15 pound test clear fishing line running through the middle. Just looks like cds hanging magically in the air. Real flashy. Hanging the things way up in a tree. Bow and arrow beats rock on a string. Have fun!

Love the wind chime idea. I want something to keep the birds out of my tomatoe and that may work. I am also kicking around a larger project idea! I have to build new raised garden beds next year so I just may start collecting old CDs/DVDs from friends that would otherwise end up in landfills and doing a mosaic mural on the raised bed sides!! It may end up not being anything great or it may be really pretty........we'll see!!

I just tried out heating the coil. I used the baking method. I put it in the oven at 180 deg. for 4 hours. I felt that 180 is still cooler than the coil is subjected to while installed on the engine. I got distracted is the reason for the four hours. It came out with no damage and I installed on the mower and it started on the first pull. I highly recommend it as you have nothing to lose if it doesn't work. Thanks for the great and easy fix. Kelly
