21. Garden Fertilizer
I have said previously how eggshells will help your plants because of the calcium that they give off. You don’t just have to add the eggshells to the certain plants that really thrive off of calcium.
In fact, you might want to consider using your eggshells as an all-over fertilizer for your garden. It is organic and added calcium and nutrients are never a bad thing in my book.
22. Kick the Cats Out
Thankfully I don’t have this problem in my garden, but I know if you live in an area that has a lot of stray cats, you could have an issue of cats using your garden as a litter box.
However, this is really quite dangerous because their waste is not good for the soil or for us to ingest. Place eggshells where they usually use the bathroom. The discomfort of walking on eggshells will usually persuade them to go elsewhere.
23. Help Catch Food in Your Sink
Useful uses for eggshells also include letting them catch food in your sink. When you wash dishes, do you put the plug/strainer in your sink to stop water from going down the drain along with food?
If so, then you’ll definitely want to consider placing broken pieces of eggshells in the strainer. It actually catches more food that way.
24. Clean Your Drains
This is an idea that should be used with discretion. Some say that eggshells are an excellent drain cleaner while others say they clog your sinks.
I’ll say try this one and see what you think. In most instances, people allow the eggshells from their sink strainers to go on down and be an abrasive cleaning tool for their pipes.
25. Give Them to the Dog
If you have a pooch for a pet, then you probably want to do all you can to get your furry friend as healthy as possible.
Then you should consider cooking your unused eggshells at 250°F for 30 minutes. Next, you’ll crush the shells and grind them into a powder. Then store them in an airtight container. When you want to give your dog a calcium boost, sprinkle a little over his food.
26. Pain Reliever
Do you ever get achy muscles or joints? If so, then you are probably used to popping an over-the-counter pill to stop the pain, or applying warmth to the sore area.
Well, next time, try letting some eggshells sit in ACV until they dissolve. This usually takes about 2 days. Then use that mixture to rub on your achy muscles and joints to relieve the pain.
27. Repair Your Cuticles
It can be hard on your hands using all of the antibacterial soaps that we use to clean our hands. It often dries our hands and cuticles out.
However, you can repair your cuticles by placing a piece of broken eggshell on your cuticle with the membrane facing down. When the shell has dried out, you’ll peel the shell off and your cuticle should be fixed from the nutrients in the membrane.
28. Clean Skinny-Necked Vases
One of the many useful uses for eggshells is cleaning skinny-necked vases. Vases that are used for holding a single rose are very pretty but often very hard to clean. In those cases, eggshells can be a great help.
You’ll just fill the vase with warm water, soap, and crushed eggshells. Then swish the mixture around. The warm water and soap will loosen the dirt while the eggshells will be abrasive and scrub the grime off.
29. DIY Ornaments
I love this idea as a way to decorate a Christmas tree or for Easter. You’ll pull some fresh eggs out of your coop or purchase them from the store.
Then you’ll gently place a hole in the bottom of the eggshell with a pin. You’ll blow the inside of the egg out and then decorate the eggs however you like. What a fun craft to do with the kids and definitely one of the most practical useful uses for eggshells!
30. Make a Baby Doll
I got this idea from my days in middle school. I took a home economics class, and we were required to keep an egg baby for a week.
We took a fresh egg, poked a hole in it with a pin, and blew the inside of the egg out. Then we made clothes for our egg baby and pretended like they were real. It is actually a great and inexpensive idea to share with your kids.
31. Tea Light Holders
This is such a fun and creative idea to decorate your home for any occasion on a budget. You just save your eggshells.
Then you can paint them and place little tea lights inside of them so they can make a creative and beautiful centerpiece. Here is the full tutorial.
32. Make Them Into a Herb Garden
I shared with you here how you can easily grow herbs indoors. This idea takes that one step further, and I think it is awesome.
You save your eggshells and then plant your herbs right inside of them. You then can grow fresh herbs on your counter right in an egg carton. Here is the full tutorial.
33. Bake in Them
Would you ever guess that you can use an eggshell to bake something inside of it? I, honestly, would have never believed it until I saw it.
And you can see it too. Here is a great tutorial on how to bake amazing cakes and brownies right inside of an eggshell. What a neat way to play tricks on your friends this April Fools Day and another idea of the many creative useful uses for eggshells.
34. Create Mosaic Art
I tried to create mosaic art one time. It was on my honeymoon (which we decided to bring my mother-in-law and 2 stepchildren with us!)
Yes, it was quite the experience, and needless to say, my mosaic art didn’t turn out so hot. However, with this tutorial, your mosaic art with eggshells can turn out great!
35. Shadow Lamp
This shadow lamp tutorial is really amazing! You can etch out an eggshell anyway you would prefer and then paint it.
Then you hold it up to a tea light and watch it create all kinds of cool scenery right on your wall. This would be a fun activity to do with your own children or in a volunteer position with neighborhood kids.
Well, you now have 35 useful uses for your eggshells. Some are very healthy and some are just for fun, but either way, they won’t go to waste and can be very functional.
How can we improve it?
