When we lived at our old house, some birds were nesting in one corner of our porch roof. We wanted to be able to see how the eggs and babies were progressing, so before the adult birds started building the annual nest, we mounted an AOL CD behind the nest angled down. This particular CD was virtually rainbow-free and acted as a mirror. Best educational use for it that I've seen!
Or you can use them as makeshift frisbees. Home decor is always an option--that bathroom wallpaper border too expensive? Mount AOL CDs back-side-out along the top of the wall and increase the amount of light reflected in the bathroom!
Q: How many poets does it take to change a light bulb? A: 1001...one to change the bulb, 1000 to say it's already been done.
