Legend has it that Bruce Lee used to eat entire eggs, including the shell. Maybe he knew something the rest of us don't. While we don't recommend you eat eggshells, here are a few unusual uses for them.
Sweeten your coffee
Add some crushed eggshells to ground coffee before brewing it to make it taste less bitter. When you're done, toss the grounds and shells on your compost heap!
Put them on your face
To restore a youthful glow to your skin, pulverize clean, dried eggshells with a mortar and pestle. Mix the powder with some egg white and spread on your skin. Allow the mixture to dry before washing it off.
Clean your house with them
Ground eggshells make a wonderful (and nontoxic!) abrasive for those tough-to-clean pots, pans, and thermoses. Mix them with a little soapy water for a powerful clean.
Unclog your drains
Keep a few ground eggshells in your kitchen sink strainer. They trap additional solids and when they slowly break down, they will help to naturally clean your pipes on their way out.
Fertilize your garden
Eggshells are rich in calcium and other minerals that help your garden thrive. Crush eggshells into tiny pieces and use them as compost.
Clear up your skin
Drop an eggshell into a small container of apple cider vinegar and let it soak for a couple of days. Dab the mixture on minor skin irritations or on itchy skin.
Start some seedlings
Fill an egg carton with empty, rinsed eggshell halves and poke a hole in each one for drainage. Then add potting soil and one or two seeds to each shell. When the seedlings are big enough for transplanting outside, just crack the shell at the bottom and plant them, shell and all. It's biodegradable!
