What makes an egg rubbery?

What makes an egg rubbery?

Egg shell is made of calcium carbonate. Vinegar is an acid – acetic acid. When calcium carbonate is exposed to an acid it reacts. This makes the egg feel rubbery.

What is a rubber egg experiment?

The little bubbles you see in the water are made of carbon dioxide gas; just like the bubbles from your vinegar and baking soda volcano. Once the shell is gone, the vinegar will cross over the semi-permeable membrane (through a process called “osmosis”) and slightly inflate the egg.

Why does an egg turn into rubber after placing it in vinegar?

These bubbles are a chemical reaction between the acid in the vinegar and the base in the calcium carbonate of the eggshell. When an acid and a base mix they form carbon dioxide which is a gas. The eggshell dissolves and leaves a soft, bendable, squeeze-able, rubber egg.

How does the bouncy egg experiment work?

How Bouncy Eggs Work: The shell of an egg is made of calcium carbonate. When you place the egg into the vinegar, you see bubbles, which is the chemical reaction of the acid in the vinegar reacting with the calcium carbonate to produce carbon dioxide.

How long does a bouncy egg last?

For just a bit bouncy, one day. If you want it medium, two days, and if you want it really bouncy, three days. How do you store the egg after the vinegar treatment? Place it in a plastic bag or any plastic container with a lid, and place in the refrigerator.

What is vinegar for egg experiment?

But what happens if the chemical prevents the thick coating of calcium carbonate around the egg from forming? We can do an experiment, using ordinary kitchen vinegar (dilute acetic acid), and see what happens to the calcium in an eggshell when it is exposed to an acid.

What happens to an egg in Coke?

After the Coca Cola and egg was left for a year, the soda reacted with the egg shell made up of calcium carbonate reacted with the acid and the result was surprising. The lumps of shell of the egg were found at the bottom of the bowl and the egg became nothing but a rubbery brown mess.

How do you make a bouncy egg for kids?


  1. Fill your container with about 1 cup of vinegar.
  2. Add about 10 drops of food coloring of your choice.
  3. Carefully place a raw egg inside each jar.
  4. When the surface of the water has a weird scummy film, the eggs are ready to take out.
  5. You can gently roll and bounce the eggs to see what happens!

How do you make eggs bounce?

What is the conclusion of bouncy egg?

Conclusions. The eggshell is dissolved because vinegar is an acid and eggshells contain calcium carbonate, which is a base. When these two chemicals are combined, a chemical reaction occurs. Carbon dioxide is formed, which is why you see the bubbles.

How do you make a rubbery egg?

The basic idea is to place a raw egg in a container of vinegar. You let the egg sit in the vinegar for a week and at the end of the week, the egg is rubbery. “But why use vinegar?” the kids asked. “Can’t we use other stuff and still get rubbery eggs?” And thus our easy rubber egg experiment was born!

What is a rubber egg experiment and why do it?

Why do a rubber egg experiment? It’s a great way to teach kids about the different parts of an egg, what their functions are, and how a chemical reaction works. So gather your supplies and get ready for a scientific exploration everyone in the family will find fascinating.

What happens when you Splat rubber eggs with corn syrup?

Instead of the egg swelling with both its own water and the vinegar which enlarged it, the corn syrup pulled the water out of the egg and into the syrup! After learning so much cool stuff about rubber eggs, it was time to splat them….I mean bounce them!

What happened to the vinegar egg in the egg experiment?

The vinegar egg had lost it’s shell was rubbery and also larger than when the experiment first took place. The corn syrup egg was developing a rubbery texture too but seemed slightly smaller than when the experiment took place. The Coke egg still had its shell and had only been dyed a brownish color.
