There are many strange and remarkable things that can be done with eggs.  You can make eggs of unusual sizes, shapes, and colors.  You can even make see through eggs and turn eggs wrinkly. 

These experiments and ideas are great for kids of all ages.  Even adults will be amazed at some of the things that can be done with eggs.  Try these experiments at Easter, on a rainy day, or anytime.  Get ready to do some really cool stuff with eggs.

Square Egg


Square Eggs


Egg Cuber

Hard boiled egg

Eggs are oval, right? They don’t have to be anymore. Make square eggs using an egg cuber.

For the best results, chill the egg cuber for about 15-20 minutes in the freezer before you use it. Boil an egg and then peel it. While the egg is still warm, put it into the cuber and put the forming plate on top of the egg. The screw the lid on tight.

Leave the egg in the cuber for at least ten minutes. Leaving the egg in the cuber longer improves the results giving you a more square egg.

This is a great project to do with kids. Children will be amazed with square eggs. You can also dye the egg and make square Easter eggs. Serve square eggs at a party or brunch. Cube a dozen eggs and build an egg fort.  Boiled eggs won’t be the same with an egg cuber.

Making Square Eggs


Naked Eggs




Raw egg

Want to take the shell off of a raw egg?  It is a simple process to create naked eggs.  First, put the egg into the cup.  Pour the vinegar over the egg so that the egg is completely immersed.  The vinegar will begin to form bubbles around the egg. 

Leave the egg in the vinegar for 2-3 days or until the shell has completely dissolved.  If the shell hasn’t dissolved, leave the egg for another day or two.  Once the shell is gone, the egg will have a yellowish color. 

Gently rinse the egg of by placing it in plain water for a few minutes.  Allow the egg to dry completely for about a day.  The egg will feel leathery.  You can even bounce it about a foot and it won’t break.

You will be able to see the yolk inside the egg.  This is a cool way to teach kids about eggs.      


Wrinkled Eggs




Hard boiled egg

Wrinkled eggs look strange, but are fun to make.  You will follow the same basic procedure as with naked eggs, except you use a hard boiled egg instead of a raw egg.

First, boil an egg.  Don’t peel it.  Place the egg in the cup and pour vinegar over it until the egg is completely submerged.  Now leave the egg for about 3 days. 

Check on the egg to see if the shell has dissolved.  Once the shell has dissolved, the egg will begin to wrinkle.  Leave the egg for another day or two if it hasn’t wrinkled yet.  It may take up to a week for the shell to dissolve and the egg to become wrinkled like a raisin.  Once the egg has wrinkled, rinse with water and allow it to dry.    

This is a strange way to peel an egg.  If you are doing this project with kids ask them if this is a practical way to peel an egg.  You can also do this experiment simultaneously with the naked eggs.  Before begin the experiment have the children predict what the results will be for the raw eggs and for the boiled eggs.

Ostrich and Emu Eggs

Giant Eggs

Ostrich eggs are pretty easy to obtain. A local farm or zoo in your area may have ostrich eggs for sale. You can also purchase them online. Many places also sell just the shells of ostrich eggs. They are much larger than normal chicken eggs and look almost prehistoric.  Let your kids guess what kind of creature would hatch from this egg.  Don't be surprised if they guess a dinosaur.   

Let your children compare the difference between the giant ostrich eggs and normal eggs. Did you know some people eat ostrich eggs? If your ostrich egg is fresh, you can cook it and eat it. One ostrich egg is about the equivalent of a dozen chicken eggs.

To boil an ostrich egg, it will need to cook for about an hour and a half. You can also scramble the egg.

Make giant Easter eggs by dying ostrich eggs. Your kids will be amazed. 

Emu eggs are also large. They look even stranger because they are blue. They can be purchased as well. So give your kids a lesson about egg sizes and colors.

Spider Egg Shells

These eggs look spooky, but taste just like normal boiled eggs.  First, pour water into a saucepan and allow it to boil. Once the water is boiling, add the eggs. Pour the frozen blueberries into the water at the same time you add the eggs. Boil the eggs for 10 to 15 minutes.

Remove the pan from the heat. With a spoon, hit each of the eggs gently so that it cracks the shell. You may want to tap each of the eggs in a few different spots to create more than one spider web pattern. Let the cracked eggs sit in the blueberries for 10 to 20 minutes to soak in the color.

Remove the eggs and rinse with water. The eggs will be a deep purple shade and will look like they have spider webs on them. You can serve the eggs with or without the shell.

They are great to serve at Halloween or for spider lovers anytime. You can also create purple Easter eggs using this recipe. You can even skip the step for cracking the eggs. Instead of spider eggs, you will have purple eggs.

The spider egg shells can be used for decoration. Place them in a jar to look like an ingredient in a strange concoction.

Okay, I'm on the hunt for egg cubers for me and all my friends! Kid's would love seeing them served that way. :)

moonlake - Thanks! The spider eggs are fun to do.

moonlake from America on April 03, 2013:

Enjoyed your egg hub. I have never heard of some of these loved the spider eggs. Voted up.

Barbara - I don't know of any way to make an egg square with the shell. The vinegar will dissolve the shell and give the egg a leathery feel and you will also be able to see the inside of the egg. Maybe you can look for a chicken who lays square eggs.

Barbara on April 07, 2011:

I am wanting to make an egg square but still in the shell, is there any way I can do this. I am soaking raw eggs in vinegar in small square tubs. Dont know if it will work, but want to freak the kids out.

QudsiaP1 - Sorry your appetite was ruined. Maybe the square eggs would be more appealing for you.

QudsiaP1 on January 21, 2011:

This has to be the weirdest thing about eggs I just came across.

What makes it worse is that I am infact, right now about to eat eggs and the wrinkled/spider eggs made me loose my appetite.

Great hub though, neat tricks to try with kids. :P

This is pretty much the strangest and best hub that I've seen. I would never... ever... think of writing a hub like this. Thank you for opening my eyes to a hobby I never even knew existed!

parrster - You should invest in an egg cuber. For some inexplicable reason square eggs taste better. Glad enjoyed the video.

Richard Parr from Australia on January 09, 2011:

Purely the title got me to this hub; and once here I was strangely spellbound. After watching the egg-cuber video with my children, I may now have to buy one; if for no other reason than use it as a conversation starter. Neat hub.
