Introduction To Egg and Vinegar Experiment:
The egg in vinegar experiment is a classic experiment used in removing the egg shell from an egg. I once wrote a post that compiled various egg experiments for kids, you might want to check it out and see all sort of things you can do with an egg.
Most of the egg experiment revolves around the use of vinegar, talk of the egg osmosis lab, the bouncy egg and glowing egg; all of them requires the use of vinegar at one point of the other.
I have decided to make a post about the egg in vinegar experiment, what’s so special about vinegar anyway? and how does it react with egg to produce it’s result. Why does vinegar have such effect on egg?
Before I proceed on the science of vinegar; let’s look at some pretty amazing egg in vinegar experiments:
Bouncy Egg: I have wrote about this experiment on several occasions on here. It’s by far one of the most interesting egg experiment I have listed on this website.
The aim of this experiment is to perfectly remove the hard egg shell from fresh eggs, and leave the outer membrane intact.
Because the egg membrane is not as fragile as the hard shell covering it (strange huh?)… The idea behind leaving the outer membrane is such that; you can stress the egg (bounce it) lightly without breaking the egg because the membrane is a little bit stronger (less fragile) as compared to the shell.
Vinegar plays a very important role in this experiment; you can of course check out the full procedure of the experiment and see what the vinegar actual does.
Egg Osmosis Lab: Whoever named this experiment is a very funny individual. Egg osmosis lab? C’mon! What happens to Egg Enlargement? Just saying…
The aim of this experiment is to show the permeability of the egg membrane and how liquid can move from a region of higher concentration to a region of lower concentration.
The experiment might take up to a week before completion; but the outcome sure worth the wait.
Vinegar also plays an important role in this experimental setup; mainly because the egg shell is impermeable to water, so the first step in the experiment is to get rid of the hard egg shell; and what better way do we have than using the egg in vinegar experiment method.
Glowing egg: This experiment is similar to the egg osmosis lab experiment. It follows the same procedure; the only twist here is just the addition of food coloring to the vinegar in which the egg is soaked.
By adding food coloring (You can add any color of your choice), when water migrate into the egg through the membrane covering it; the coloring would eventually migrate in together with the water, and as a result, it would give the egg a completely new color.
Using this experiment; you can have green egg, yellow egg, purple egg or red egg, and use them for illustration purpose.
There are other interesting experiments that can be done vinegar and egg, most of those experiments have been discussed on this website at a point in time; so check through the links and you would find the compilation of various egg experiments.
Egg in Vinegar Experiment: Caution
The purpose of soaking eggs in vinegar is to remove the egg shell and along the process show the reality of some basic science laws and theory, while this is fun and educating, it should be noted that vinegar egg are not suitable for consumption.
Once you’re done with the experiment, please discard the egg where no one can consume it; not even your pet.
Other Uses Of Egg and Vinegar Experiments?
We’ve seen various experiments on how vinegar can be used in removing the hard egg shell leaving out the membrane.
What other ways can we use vinegar effectively especially in the kitchen?
Another effective way of using vinegar is boiling eggs with vinegar. This has been showing to make the peeling process very easy.

The Science Of Egg in Vinegar Experiment:
Now that we know the different kind of stuffs that can be done by initiating a reaction between an egg hard shell and vinegar. Let’s look behind the scene of the result, and see the explanation (science) behind the outcome of the reactions between an egg shell and vinegar.
An egg is made up of three major parts, from inward outward; we have the yolk, the albumen and the egg shell. In between the egg shell and the whites (albumen) is an outer membrane which is a sac like covering that separates the egg whites from the egg shell.
We are more interested in the egg shell part.
The egg shell is made up of calcium carbonate which is a chemical compound responsible for the hardening of the egg shell.
Vinegar on the other hand is made up of about 3% acetic acid (The remaining 97% is mostly water).
When the acetic acid in vinegar reacts with the calcium carbonate that makes up the egg shell, it results into formation of carbon dioxide (This is the bubble you see during the experiment).
This gas escapes into the atmosphere as the reaction continues until the calcium carbonate in the egg shell is completely exhausted! Leaving only the out membrane covering the egg whites.
That’s the science behind the reaction of vinegar with egg shell.
