Eggs contain something called "calcium carbonate". This is what makes them hard. Vinegar is an acid known as acetic acid. When calcium carbonate (the egg) and acetic acid (the vinegar) combine, a chemical reaction takes place and carbon dioxide (a gas) is released. This is what the bubbles are made of. The chemical reaction keeps happening until all of the carbon in the egg is used up -- it takes about a day. When you take the egg out of the vinegar it's soft because all of the carbon floated out of the egg in those little bubbles. Since the egg shell is made out of "calcium carbonate" and is "eaten" up by the acidic vinegar. Then leaving behind only the inner membrane and giving the egg a rubbery feeling. The egg shell is almost completely see-through and squishy.
Immediately after we place the raw egg in the vinegar, bubbles start to form around it. After 24 hours the shell will be gone and portions of it will be floating on the surface. The egg remains intact because of the thin see-through membrane that is normally between the shell and the egg white. Also, the size of the egg has slightly increased.
Vinegar is made of acetic acid and eggshells are made of calcium carbonate. Acetic acid reacts with the calcium carbonate and dissolves the shell. Next, the water from the vinegar moves through the membrane into the egg because the membrane is semipermeable. What this means is that some small particles can pass through the microscopic holes in the membrane, but other larger molecules cannot. Water molecules are small enough to move through the membrane and balance the water levels on each side.
Because vinegar is an acid, when an egg sits in vinegar over a long period of time, the vinegar will eat away at the shell of the egg. It will ultimately dissolve the shell and leave the egg yolk and white encased in the filmy skin that is just inside the shell.
It is an interesting science experiment to do with kids. However it takes days or weeks to fully dissolve the shell.
Something fun to do afterwards is, after leaving the raw egg in vinegar for 48 hours, put it in a solution such as colored salt water (just make your own), colored tap water, or molasses for at least 24 hours. Then remove the egg and cut it open...see what happens!
The acetic acid in the vinegar has a chemical reaction with the calcium carbonate in the shell. The calcium carbonate ends up in the foam and bubbles on top of vinegar.
it makes the boiled egg soft like a bean bag . so when you drop it on a floor it will not bounce .

What causes eggs to become rubbery?
you boil it
What is a coclusion for a science fair project?
a conclution for a science fair project means, if ur hypothesis was right for example: the topic "Rubbery Egg" the conclution was that the egg becomes rubbary wen it is put in vinegar.
How do you make wood floors less slippery?
Use vinegar.
If you put an egg into colored vinegar would the egg change color?
Well yeah. It's called dying eggs. :P that will actually be awsome
What happens if you put an egg in vinegar?
What happens is the egg will soften and the shell will eventualy dissolve off of the egg and then the egg will get a rubbery feel. Chances are you might be able to bounce if you try. This is not me telling you to bounce it.
How do you make the eggs jump?
To make eggs rubbery, you have to soak a hard-boiled egg in vinegar for around 3 days.
What causes eggs become rubbery?
If it bounces then you probably overcooked it they are rubbery though^yes...but If you soak the egg in white vinegar for 48-72 hours, the shell will disolve the leave the membranes intact. The membranes make the egg rubbery and will in turn bounce(it'll feel like a bouncy ball)
Can eggs bounce?
yes if you keep it in vinegar for 7-8 days. the acids in vinegar break down the calcium carbonate in egg making the egg soft and rubbery. it can bounce then
Why does vinegar make bones rubbery?
Vinegar makes bones bend because the acetic acid eats away at the calcium in the bones.
What causes eggs to become rubbery?
you boil it
What happens when you put eggs in vinegar?
If you put a raw egg in vinegar the egg shell will disolve and will leave the whole inside rubbery. This happens from acetic acid. Acitic acid is used as a solven in rubber, plastic, is chief acid of vinegar. (you could hear more about acetic acid if you ask a Qustion about it.)
What is made form a mixture of nonfat milk and vinegar?
rubbery substance .
What is the point of soaking an egg in vinegar?
to turn it into a rubbery substance and to preserve it
What liquids are best for making an egg's shell rubbery?
White vinegar is the best liquid for making an egg shell rubbery. The vinegar must be changed daily to prevent mold from growing on the egg shell.
How long does it take for vinegar to dissolve bone in vinegar?
it takes up to 5 to 7 days to turn rubbery.
HOW TO COOK poached eggs?
In order to poach eggs the first thing one needs is to bring water to a boil. Once the water is boiling add 1 or 2 teaspoons of vinegar to it. Crack the eggs into the water and vinegar and remove the pot from the burner. Let the eggs sit in the water for about 4 minutes.
How does heat affect eggs?
Heat denatures the proteins in eggs, causing them to change from a liquid to a solid state. This is why eggs go from liquid to solid when cooked. Overcooking eggs can make them tough and rubbery due to the proteins continuing to coagulate.
