12 eggscellent things you can do with eggshells

Take a crack at these eggshell reuses:

1. Less bitter coffee
   Add an eggshell to the coffee in the filter, and your morning coffee will be less bitter. The spent coffee grounds, eggshell, and biodegradable paper filter are then conveniently ready for the compost pile.
2. Natural drain cleaner
   Keep a couple of crushed eggshells in your kitchen sink strainer at all times. They trap additional solids, and they gradually break up and help to naturally clean your pipes on their way down the drain.
3. Nontoxic pest control in the garden
   Scatter crushed eggshell around your plants and flowers to help deter plant-eating slugs, snails, and cutworms without using eco-unfriendly pesticides. Also, deer hate the smell of eggs, so scattering eggshells around the flowerbed will help keep Bambi away from your begonias.
4. Egg on your face
   Pulverize dried egg shells with a mortar and pestle, then whisk the powder in with an egg white and use for a healthful, skin-tightening facial. Allow the face mask to dry before rinsing it off.
5. Eco-friendly household abrasive
   Shake up crushed eggshells and a little soapy water to scour hard-to-clean items like thermoses and vases. Crushed eggshells can also be used as a nontoxic abrasive on pots and pans.
6. Eggy, crafty projects
   "Blow out" the inside of a raw egg, and paint/decorate the hollow shell to make your own Faberge eggs or other craft projects. Pieces of egg shell (plain or dyed) can also be used in mosaic art projects.
7. Clever Jell-O and chocolate molds
   Carefully fill "blown out" eggshells (see above) with gelatin or chocolate to make unique egg-shaped treats. Peel away the eggshell mold before serving, or serve as is and let your guests discover the surprise inside.
8. Treat skin irritations
   Dissolve an eggshell in a small jar of apple cider vinegar (takes about two days) and use the mixture to treat minor skin irritations and itchy skin.
9. Compost for naturally fertilized soil
   Eggshells quickly decompose in the compost pile and add valuable calcium and other minerals to the soil in the process.
10. Membrane home remedies
    The super-thin membrane inside the eggshell has long been used as a home remedy for a wide range of ailments, from healing cuts to treating ingrown toenails.
11. Splendid seedling starters
    Fill biodegradable eggshell halves with potting soil instead of using peat pots to start seedlings for the garden. And an egg carton on the windowsill is the perfect way to start a dozen tomato seedlings in shells before transplanting to the garden in the spring.
12. The fuel of tomorrow?
    Just when your brain was totally fried by all my ingenious reuses for eggshells, researchers at Ohio State University recently discovered that eggshells might be the key to producing affordable hydrogen fuel. I've heard of walking on eggshells, but maybe some day we'll be driving on them too.
