Rubber Egg Chemical Reaction Experiment
In this fun and easy science experiment, we’re going to explore and investigate chemical reactions by making the shell of an egg disappear leaving a rubber egg behind.
Materials:
- Vinegar
- Egg
- Small glass or cup
Instructions:
- Place your egg in the glass.
- Cover the egg with vinegar.
- Wait six to seven days.
- The shell of your egg will have disappeared. You may have to rinse some of the shell residue from your egg.

How it Works:
The eggshell is made of calcium carbonate. A chemical reaction occurs with between the vinegar and calcium carbonate. This reaction will create carbon dioxide. If you look closely, you may see tiny bubbles forming on the side of the eggshell and float to the surface. The reaction will eventually dissolve the eggshell. The membrane of the egg will remain and the egg will have a rubbery look. Carefully investigate the egg but understand it can still easily break and make a mess.
Make This A Science Project:
Leave the egg for several weeks in the vinegar. Place the vinegar and egg in the refrigerator to see if temperature effects the experiment.
