Egg Science Experiments
There are many easy and fun experiments that can be done with eggs. These are great to do with kids of all ages at home or at school. Most of the materials are probably already in your kitchen.
You can suck an egg into a bottle, make a bouncing egg, tell whether an is raw or boiled, make an egg float, and even hold books with egg shells. So grab a carton of eggs and try some eggs-tremely cool science experiments.
1 hard-boiled egg
1 raw egg
Ever wondered how you can tell the difference between a hard-boiled egg and a raw egg? Just spin them to figure it out. Place a hard-boiled egg and a raw egg on the table. Spin each of them and observe what happens. The boiled egg will spin faster. The raw egg will spin slowly. The reason for this has to do with the insides. The boiled egg is one solid piece. Therefore the whole egg spins in the same direction. The raw egg has liquid inside which moves separately from the shell. The movement of the inside of the raw egg keeps the whole egg from spinning quickly.
Observe what happens when you try to stop the spinning of the eggs. Spin the eggs and then put your finger on them to stop them. The boiled egg should stop immediately. The raw egg will keep spinning for a moment because the liquid inside the egg will keep moving.
Egg and Salt Experiment
2 clear glasses
2 raw eggs
Will an egg sink or float in normal water? What effect will salt have? Place the two glasses of warm water on a table. Add about 10 heaping tablespoons of salt to one of the glasses and stir until the salt is dissolved in the water.
Place an egg in each glass and observe what happens. The egg in the normal water will sink to the bottom while the egg in the salt water will float to the top.
Expand on the experiment by mixing the two types of water. Remove the eggs from the glasses. Empty about half of the salt water. Then pour the plain water into the salt water cup up to the amount the glass had before. Place the egg in the cup. The egg will float in the middle of the cup.
Make the egg rise to the top again by removing the normal water. With the egg still in the glass, begin slowly removing the water a spoonful at a time. The egg will rise higher and higher as each spoonful is removed.
The egg floats in salt water because of its density. Saltwater is denser than the egg thereby causing the egg to rise to the top. The egg is denser than normal water, though, which is why it sinks to the bottom when in the cup of normal water.
Egg in the Bottle Experiment with a Twist
Egg in the Bottle
Glass bottle or jar with a narrow opening
Hard-boiled, peeled egg
In this experiment, the egg will be sucked into the bottle. First, sit the egg in the mouth of the bottle. The egg should sit in the opening without falling in. Now move the egg away and light the piece of newspaper and drop it into the bottle. Quickly place the egg over the opening of the bottle with the narrow part of the egg pointing down into the bottle.
As you watch, the egg will get sucked down into the bottle. Now try to get the egg back out of the bottle. It won’t be able to go back through the opening without breaking apart.
The egg gets sucked into the bottle because the fire causes the air pressure inside the bottle to become less than the air outside. The air on the outside of the bottle is greater than the air in the bottle, so the egg gets sucked in. The egg won’t come back out of the bottle easily because the pressures have stabilized and there is no force acting on the egg.
For a cool trick to get the egg back out of the bottle, check out Steve Spangler Science.
The Strength of Eggshells
3 Raw eggs
A Stack of books
Paper towels or cleaning cloths
Before beginning the experiment, predict how many books the eggs will support before breaking. Unfold the sheets of newspaper and lay several sheets flat on a table or countertop. Position two of the eggs in the middle of the newspaper so that they are a few inches apart. Now lay one of the books on top of the eggs. Keep placing books on top of the eggs until the eggs crack.
Now gently crack the remaining egg with the knife so that the egg is in two nearly equal parts. Clean the yolk out of the shell halves. Spread clean newspaper on the tabletop. Lay the egg halves in the middle of the newspaper a few inches apart. Now lay a book on top of the eggs. Keep placing books on top of the eggs until the shells crack.
Did the eggshells support more weight than you had predicted? The curved shape of eggshells distributes the weight of the book over the entire egg so it is able to support more weight than a single point could.
Walking on Eggs
Large carton of eggs
You can give the eggshells a true test of strength by walking on them. The principle is the same as walking on a bed of nails. The weight is distributed enough that the eggs won't break easily.
The experiment should be done somewhere that will be easy to clean in cases of breaks. Bare feet are also best so socks and shoes won't get egg on them either.
Just open up the carton and have the kids step up on the eggs. If you have more than one carton of eggs, put them together and the kids can walk back and forth.
The eggs will hold the weight of a child but will break with the full weight of an adult. You can experiment to see how much weight the eggs will hold before breaking.
Place the egg into the cup. Pour vinegar into the cup so that the egg is completely submerged. Let the egg soak in the vinegar for 2 to 3 days. Remove the egg from the cup. Check to make sure the shell has completely dissolved. The egg should feel leathery. Wash the egg with water. Let the egg dry completely for a day or two.
When the egg is dry you can bounce the egg. It will bounce about a foot without breaking. Test to see how high you can bounce it before it breaks. You could also test whether the surface you bounce the egg on affects how high it can bounce.
The egg bounces like a ball because the acidic quality of vinegar dissolves the shell of the egg. You can try to trick your friends and family by “dropping” the egg.
Soda (Any brand, but must be regular and not diet)
Gently use the pin to poke a hole in the top and the bottom of the egg without breaking the shell. Blow the insides of the egg out through one of the holes. If the yolk won’t come out, gently make the hole bigger.
Fill the cup with the sugary soda. Place the eggshell into the cup and leave it overnight. Have the kids predict what will happen to the shell. Check on the egg the following day. The shell will be soft. Expand on the experiment by asking what soda can do to other things like teeth.

can u do the rubber egg with something else hihihihihhi
Olivia on September 21, 2019:
Can you have normal vinegat or do you need white vinegar xxxx you are realy good at these things ❤
Stephanie on May 30, 2019:
Can you please make one were we can play with the raw egg

could you do one with sprite
babushka_10000 on January 18, 2019:
k these eggs without shells arent even cool. I live in a chicken coop with my pretty ladies and i see them literally all the time. i betcha someone from the city made this and thought it was so cool. if u wanna see eggs without shells just hobble on over to my neck of the woods and i'll let you city slickers gawk at em for as long as y'all want

Francis - Each experiment has different results. You should be able to read what happens toward the end of each description.
Francis on May 25, 2013:
What was your result of this experiment
Candace Bacon (author) from Far, far away on March 14, 2013:
Jenni - It actually does have to do with air pressure. The vacuum created inside the bottle is less air pressure than the air outside the bottle. I updated my explanation so it is a bit more clear. Thanks.
Jenni on March 12, 2013:
Hi, some great content for my easter egg science blast thanks, just wanted to comment on your explanation as to why the egg gets sucked into the bottle after the newspaper burns. As the paper burns, oxygen is consumed, therefore creating a vacuum which sucks the egg inside, rather than anything to do with air pressure. If the air inside were seeking a release, the pressure would rather force the egg out of the top, not suck it in! Thanks for the great ideas.

Courtney - You can definitely use this as a science fair project. I don't know what the criteria he needs to use are exactly, but in science fairs they usually look for variables in the experiment. He could also test a couple of different ways of trying to see inside the egg. For instance, trying a couple of different types of vinegar to see if it makes a difference or using another type of ingredient or chemical to see if the shell dissolves as well. Steve Spangler science has some great ideas with this experiment and how to use it for a science fair: http://www.stevespanglerscience.com/experiment/nak...
Courtney on March 03, 2012:
So thinking of trying the "naked egg" experiment with my son for his science fair project at school. Do you think that this would be possible? We have to use the scientific method for ther project. Was thinking his question could be something along the lines of "How can you see what's inside an egg shell without breaking it" Then he could research what the shells are made of and so on and so forth. So what say you... yay or nay? Thanks for any input!!

I was eggstremelyy impressed by your bad pun- You get a thumbs up for bad punnery- My fav egg-speriment ( heheha)
is spin a raw and boiled egg then gently stop them the raw egg will continue to spin due to the cyntrifugal yolk force- Eggcellent Hub
