Naked Egg Experiment
What You Will Need:
a soft-shelled (not hardboiled) egg

a clear plastic cup


24 to 48 hours

flashlight (optional)
What You Need to Do:
1.Place a raw (not hard boiled) egg in a clear plastic cup or other container.

2.Fill the container with white vinegar.

3.Check on the egg in about 12 hours. You should notice bubbles have formed on the egg and/or that there is foam on the top of the liquid.

4.Pour out the vinegar and replace it with new vinegar. Leave the egg to soak for another 12 to 24 hours.

5.After two days, use a spoon to carefully remove the egg from the container. By now the eggshell has likely completely dissolved, leaving behind a sort of egg water balloon, so you do not want to remove the egg with your hands.

6.Rinse the egg gently with water.

7.Shine a flashlight behind the egg. Since the eggshell has dissolved, all that left is the membrane. The egg should be translucent and nearly glow when the light shines through it.

Hypothesis: The presence of the acid in the vinegar will force the egg shell to soften and dissolve.

Bubbles forming on the shell and foaming.

Egg is soft after egg is washed and shell has been removed.

When light is shined upon the egg it is transparent.

Conclusion:Results from the experiment was exciting. The hypothesis was correct. No shell remained on egg. When egg was washed the egg was transparent. From this experiment I learned that there is more than one way to remove the shell off an egg.
