Eggshells. One of nature's greatest feats of protective packaging. One the package is opened and you've consumed the egg inside, though, what do you do with that shell?
Well, one of the things that makes eggshells so nearly perfect is their after market uses. Here's half a dozen of the best ones that I use them for regularly:
1 – Compost them. This one is the most obvious and probably the second most common thing for the empty shells to end up becoming (next to just landfill). Eggshells are a rich source of calcium and mineral supplements to your compost. To speed up the breaking-down process, crush the shells.
Many old-timers would dry the shells thoroughly, saving the powder until they had a quantity of it, and then spread it over a field or pasture and let it "soak" into the soil. This ads rich calcium to the soil and plant life and makes for excellent grazing pasture once it's been integrated into the soil.
2 – De-bitter your coffee. If you hate bitter morning coffee, you can use an eggshell to make it less so. Just put a chunk of an eggshell to the coffee grounds in most any kind of coffee maker (obviously, this doesn't work with instant coffee). The shell absorbs some of the acids in coffee that make it bitter. Plus, when you're done, the paper filter, grounds, and shell are perfect additions to your compost.
