Egg In Vinegar Experiment For Kids To Learn Acid-Base Reactions

Bouncy Egg or Rubber Egg Experiment For Kids

Science is all around us! We experience scientific phenomena every day with things around us knowingly or unknowingly. Science is one such subject which can be learnt with constant experimentation with objects that are found in our surroundings. Young children find it amazing when science is introduced to them as a subject in the early stages. They would be even more amazed when you make them conduct simple science experiments. 

One such experiment is the egg in vinegar experiment. Eggs are used on a daily basis for breakfast purposes. What if we tell you that you can use the same egg to conduct an easy science experiment which will blow your kid’s mind! Here, we will provide guided instructions on how to conduct the egg in vinegar experiment. Try this and other super cool science experiments for Kids to do at home today!

Egg In Vinegar Experiment – Materials Required 

All the materials required for the egg in vinegar experiment can be easily sourced from a general store or from your own kitchen!

Primarily, you will need these three materials. Couple of raw eggs, vinegar and a jar.

Steps To Set-Up The Egg In Vinegar Experiment

Step 1: Take a jar and place an egg in it. Now cover this jar using some household vinegar. The vinegar used to cover the jar can also be covered to produce colorful effects!

Step 2: Patiently observe the result with your child.

Step 3: A few bubbles will be formed on the eggshell due to the reaction between the acid in the vinegar and calcium carbonate on the egg shell.

Step 4: As the egg sits in the jar covered with vinegar for a longer period of time, it gets larger. Later the eggshell dissolves and turns into a rubber egg which is soft. This rubber egg is easy to bend, squeeze and it can also bounce! You will have a blast with your child after conducting this bouncy egg in vinegar experiment!

Step 5: Wait for 2 days then take the eggs out from the jar and rinse it.

Conduct An Interactive Session With Your Kid After The Completion Of The Vinegar In Egg Experiment

Your kid will have a lot of questions after the completion of the egg in vinegar experiment. Wait for them to ask the follow-up questions or you can ask them a few questions beforehand to spark his/her curiosity!

You can ask these following questions mentioned below:

  • Does the egg feel hard or soft?
  • Do you notice any difference between this egg and a regular egg?
  • What do you think happened to the egg when it was covered with vinegar?
  • Why do you think that happened?
  • Did you learn anything new from conducting the egg in vinegar experiment?

Science Behind The Egg In The Vinegar Experiment

A mineral called calcium carbonate is present in human bones which makes our bones stronger. This same mineral is also present in the eggshell. When vinegar is added to the egg, bubbles are formed due to the chemical reaction between the base of the calcium carbonate and the acid present in the vinegar. Co2 or carbon dioxide gas is formed due to the reaction between the acid and the base. As long as the egg sits in the vinegar covered jar, they become squishy and hard like rubber that makes them bounce!
