- What took place to create the egg bouncy, soft, and rubbery? Calcium carbonate is the mineral that makes up eggshells. The acid in the vinegar reacts with the base, calcium carbonate, in the eggshell when you add the egg to the vinegar. Carbon dioxide is created as a result of the calcium carbonate and vinegar’s chemical interaction ( CO2). This reaction also dissolves the eggshell, resulting in a rubber egg that is bouncy, soft, and squishy!
- However, how did the egg become larger? Some of the water in the vinegar is absorbed by the egg’s membrane as it sits in the solution. Osmosis is the name of the process that takes place to balance the water concentration on both sides of the membrane. The size of the bare egg rose as a result of the water flowing through the membrane.
Why does vinegar make an egg rubbery?
An acid is vinegar. Calcium carbonate is the main component of eggshells. The eggshell will disintegrate if you soak it in vinegar because it will absorb the acid and break down. Carbon dioxide gas, which is created from the calcium carbonate, will enter the atmosphere. The soft tissue that lined the eggshell’s inside is all that is left. It’ll bounce back!
Idea for a Science Experiment Create three jumping eggs. One egg should be submerged in vinegar for 24 hours (one day), 48 hours (2 days), and 72 hours (3 days). What color are the eggs after soaking? What happens when you try to bounce each egg? Tip: JUMP OUTSIDE!
How long does it take an egg in vinegar to become rubbery?
Each container should be marked to indicate whether it contains a hard-boiled or uncooked egg. Each container should hold one egg. Fill each one with enough white vinegar to completely enclose the egg. About two days will pass while the eggs are in the vinegar. Each egg should be checked every day to see if it has turned rubbery. If necessary, add vinegar to keep the eggs submerged. The majority of eggs will become rubbery in one to two days, but some may need a third.
What transpires if an egg is left in vinegar too long?
Despite their reputation as being delicate, eggshells are actually incredibly durable. Eggs are difficult to break because of how birds have evolved. Of course, that does not imply that they can withstand being shattered with a hammer or being dropped from a great height. However, the calcium carbonate that constitutes an eggshell is extremely resilient.
Just before the egg is ready to be laid, a healthy bird’s body manufactures calcium carbonate to coat the fragile membrane and yolk. What transpires, though, if the chemical hinders the formation of the egg’s thick calcium carbonate shell?
With the use of common kitchen vinegar (dilute acetic acid), we may do an experiment to find out what happens to eggshell calcium when it is exposed to acid.
- Put vinegar in the entire glass. Make sure there is enough room so that you can add the egg without disturbing the vinegar.
- Examine the egg’s exterior. What does the shell feel like when you carefully touch it? Can you give it a light fingernail scratch? Does something occur?
- In your science journal, make a forecast. Do you anticipate anything happening to the egg in the vinegar? Change or no change? What might alter? When do you think you’ll start noticing a difference?
- Put the egg into the vinegar-filled glass with caution. You might need a spoon to assist you. The egg may float in the liquid for one or two minutes before sinking. After timing how long the egg spent in the vinegar, monitor it for a while. Have you already noticed a change?
- Keep an eye out for bubbles on the eggshell’s surface. What do you suppose the bubbles could be coming from? In your science journal, note your prediction.
- Before rechecking, let your egg soak in the vinegar for at least an hour. Note the time and any fresh alterations to the egg. Do you see any new bubbles? Exist any additional changes?
- You can check on the egg every few hours. Make careful to include the date, any recent modifications, new hypotheses, and unanswered questions in your science journal.
- You will eventually notice a layer of white foamy froth forming on top of the vinegar. This is constructed of layers of eggshell calcium carbonate. Draw an image of the egg at this time in roughly 24 hours. What has altered? Why should I leave it in the vinegar, in your opinion?
- You can gently scrape the eggshell with your fingernail once more after carefully removing the egg, rinsing it, and drying it. What transpires? Watch out, the eggshell will be much more fragile!
- If you soak the egg in vinegar for around 36 hours, the acetic acid will finally dissolve all of the calcium carbonate, leaving only the soft membrane and yolk. Do you believe an egg could hatch if its eggshell was considerably softer and weaker? why not

By taking your decalcified egg and seeing what occurs when you submerge it in another liquid, you can further your experiment.
Remove the decalcified egg with care from the vinegar, then carefully rinse it with water. Be cautious because it is likely to shatter.
Put a different liquid in a glass. Try soda, plain water, corn syrup, salt water, or something else. Make sure to get permission from an adult before experimenting with chemicals and kitchenware.
Record the time you put the decalcified egg in the new liquid after placing it there. In your science journal, anticipate what will happen to the egg in the new liquid at this point. Before checking on the egg, give it at least an hour in the new liquid. What has changed? In your science journal, mark the adjustments and the date.
After 12 hours, check on the egg once again. Keep track of the time, any adjustments, and any new inquiries in your science journal.
Do you believe that anything can regenerate the calcium eggshell after it has been damaged? If not, why not?
When birds eat other animals that have consumed certain pesticides, such as DDT, they accumulate in the bodies of the birds. The chemical lingers in the bird’s body rather than leaving it and alters how it operates, making it more difficult for them to produce as much calcium. What potential effects do you believe this might have on bird babies?
What effects does vinegar have on the egg?
Students describe how an acid affects an eggshell in this assignment. An acid-base reaction occurs when vinegar is added to eggshells. The inner semi-permeable membrane remains intact when an egg is submerged in vinegar after the shell has broken down.
The solid calcium carbonate crystals in the eggshell are a base that are broken down into calcium and carbonate by vinegar’s acidity. While the carbonate continues to form the bubbles you see, the calcium ions, which are atoms missing electrons, continue to dissolve in the vinegar.
The membrane that lines the interior of the shell is unharmed by the acidic vinegar. The egg swells because some of the vinegar osmotically permeates the membrane. The yolk may be seen sloshing around in the white of the egg if you shake it. The contents will leak out if the membrane splits, just like they would with a raw egg, except that now they have been “pickled” with vinegar.
Younger students might believe that the membrane has “changed” into the outer shell. Remind them that the inner membrane and the outer shell are two entirely distinct layers. To demonstrate the layers, crack an egg that is still raw.
- What are the bubbles on the egg’s surface when the vinegar is initially applied?
- What is the evidence for chemical change?
- What reaction causes the shell to dissolve?
- What prevents the egg’s contents from escaping?
- Is there a variation in the egg’s size between the start and end of the experiment? What changed this situation?
What To Do
Identify a “a station for pouring vinegar at your desk so you can keep an eye on how much the students are consuming (to avoid wasting).
Repetition of the same activity with your pupils will result in a few more students “To serve as a control in the linked activity, use naked eggs. Osmosis: Naked Eggs. For this task, retain the pupils’ bare eggs as well.
- Calculate the egg’s center section’s circumference.
- Put the egg in a container.
- Store the egg in a secure location after covering it with vinegar. At the shell’s surface, bubbles ought to start to form.
- The following day, scrape the egg out of the vinegar using the large spoon.
- Throw away the used vinegar.
- The egg should be covered in fresh vinegar and kept in a secure location.
- For roughly 27 days, check on the egg every morning without taking it out of the jar. After the first day, the vinegar just needs to be changed.
- The egg should be transparent but essentially egg-shaped after a week.
- If your teacher gives the okay, don’t break the egg—you might want to use it for another experiment!
- Compare how orange juice, cola, ordinary water, and vinegar affect the eggshell. What features do the three liquids share? How do they differ?
- Try the identical procedure with a hard-boiled egg. The eggshell will dissolve in the same manner, leaving behind a rubbery egg that, if thrown from a height of less than 50 cm, should bounce.
What happens in the rubber egg experiment?
Prepare yourself for a simple science experiment that will leave you scratching your head and wondering how, Play fans! We’ll transform a regular egg into a rubbery, springy egg!
- An Egg
- jar or glass
- Clear Vinegar
Step 2: Pour enough white vinegar into the container or jar to completely submerge the egg.
3. Be patient! For one to three days, leave the egg in the glass. Ask your child open-ended questions about what they see, think is happening, etc. while you watch the egg each day. When the egg starts to become slightly transparent, you’ll know it’s ready.
Step 4: Carefully remove any extra shell that may be on the egg and remove the egg gently from the glass before running it under running water.
Step 5: Take note of the egg’s new appearance and texture. It has a springy feeling to it! Watch the egg bounce around when you drop it off the table between one and two inches high. However, if the egg is dropped from a height that is too great, it could result in a messy game.
What the Science Says: An egg’s shell is composed of calcium carbonate. You notice bubbles when you put the egg in the vinegar because the acid in the vinegar is reacting chemically with the calcium carbonate in the egg shell to form carbon dioxide. Because some of the vinegar is being absorbed by the egg’s semi-permeable membrane, you can also see the egg growing larger while it sits in the vinegar.
Is a vinegar-soaked egg edible?
An evergreen gastronomic marvel is the egg. The yellow for our cakes and the sunny sides for our dishes come from it. Even uncooked food can be consumed.
You most likely did if you were on Twitter a few weeks ago. After someone shared a clip from a movie on the Facebook page 5-Minute Crafts, the absurd term spread around social media.
To sum it up: Put an egg in vinegar, then return the next day. It lacks a shell and is larger. Put maple syrup on the egg. Ignore it. Look at it now—it has grown once again. Put some water on it. Add blue dye. Do nothing on a third day. Is it greater? Yes, it is bigger now.
As the video became increasingly popular, several inquiries “Being the most common and evident is the reason. However, another issue sparked my interest.
In fact, the egg is larger. Is it still edible after being soaked, sugared, and vinegared?
Experts on food safety say the short answer is no. Most eggs in the US can only be left out of the fridge for two hours, or one hour if the kitchen is over 90 degrees. Nevertheless, calculated risks are justified when they advance research and journalism.
I used the 5-Minute Crafts method to find the answer to my question, making the decision to only eat a tiny piece of the fried product.
I started by putting an egg in apple cider vinegar along with a backup egg. Some people might recall this process from elementary school. The calcium carbonate in the shell dissolves after being broken down by the vinegar. Within 24 to 48 hours, the acidic liquid evaporates, leaving an egg that is just membrane-bound.
To be honest, I don’t understand the syrup stage. It seems completely useless. The egg absorbs some of the water in the vinegar through osmosis once the vinegar dissolves the egg’s shell. However, the egg has a limited capacity for absorption, and good maple syrup only contains a little amount of water. Nevertheless, the video makes the claim that the syrup makes the egg bigger.
Video is false. It did, at least, when I used the Signature Select brand. I had a deflated yolk balloon after the water in the egg leached into the maple syrup. I found with the backup egg that the egg can absorb the food dye without the syrup stage as well. I believe it is safe to say: omit the syrup stage.
It was time to cook after allowing the egg to soak once more, this time in blue water.
It was both remarkable and unsettling to pop the inflated membrane to find that the coloured water had colored the egg’s interior but had left the yolk uncolored. The yolk cooked quite regularly, but the strangely foaming whites were almost creamy and incredibly sweet. Although the umami flavor was introduced, it was not typically found in eggs. the core was also sweet. The larger egg, fried to medium, is alarming and just barely funny. But ultimately completely inedible.
The absurd physics that underlies this “Craft, though, never loses its allure; it’s a humorous reminder that cooking is ultimately chemistry at any age.
