I like many of you I suspect have old CDs or DVD discs laying around from failed copying attempts or outdated programs. I have used these for a couple of years now as bird deterrents in my orchard and garden areas. They, when hung buy a thin wire or string twirl around reflecting many colors of the spectrum thus startling the birds and help keep them away from the ripening fruit. The wife uses them for coasters under her flower vases in the house also. Great way to recycle another otherwise wasted resource. I've mentioned this before, that I use a bright yellow piece of hard plastic covered with vaseline, nailed to a stake in the garden to attract flying pests and trap them before they can damage the vegetables. Especially good for bugs that are attracted to the yellow blooming flowers of tomatoes, squash and melons.
