Eggshells are a wonder of nature. They are the perfect packaging for bird babies and the food they need. Eggshells are full of calcium.

I didn’t know they were also good for repelling bugs and deer, and I certainly have never thought of putting them in the coffee! Find twelve ways to use eggshells at The Daily Green. Link -via Digg
