The Naked Egg

The project is about how vinegar (CH3COOH)
can remove the shell from an egg. What
we are trying to find out is how can you
remove the shell from an egg only using
vinegar. In our procedure we clearly explain
how many eggs to use, how large the jar
and how much vinegar to put in the jar.
The project we are performing is the naked egg.
In this experiment we are tempted to remove the
shell from a raw egg without breaking it. We
used 2 eggs, jar, vinegar, notebook paper. In this
experiment we performed how to remove the shell
from a raw egg. We were interested in this
project because we wanted to know another way
to remove the shell from an egg without cooking
If the egg is in the vinegar then the shell will
dissolve with still a little bit of the egg shell left.
1. Place the egg in a tall glass, jar or a plastic cup and cover the egg with
2. Leave the egg in the vinegar for a full 24 hours. Look closely. Do you
see any bubbles forming on the shell? If you do then cool its working
3. Change the vinegar on the second day. Carefully pour the old vinegar
down the drain and cover the egg with fresh vinegar. But remember,
use your hand to catch the egg so it does not fall down the drain. Place
the glass with the vinegar and egg in a safe place for a 24 hours! Don't
disturb the egg, but pay close attention to the bubbles forming on the
surface of the shell.
4. Pour off the vinegar and carefully rinse the egg with water. The egg
now looks transparent because the outside shell is gone! The only thing
that remains is the membrane of the egg or a little bit of the shell.
Glass Jar or Plastic Jar
Once we put the vinegar inside the jar with the egg
bubbles started to form.
Some of the bubbles are leaving the egg but they still
surround the egg in the rim of the jar.
Big chunks of bubbles are removing from the egg
Giant pile of bubbles on top of the egg
Some of the shell is peeling after we left it in the
vinegar for 12 hours.
Time (in hours) Observation
1 hour Bubble are starting to form.
2 hours Bubbles are surrounding the egg inside the
12 hours The shell is coming off.
20 hours The yolk can be seen .
21 hours The shell is still coming off .
22 hours The shell is partly off.
23 hours The shell is almost off.
24 hours The shell is completely off.
In our data it shows how the egg looked every hour.
In the first hour nothing really happened to the
egg. In the second hour the shell started to
dissolve. When it was the last hour the shell was
I would like to give thanks to Ms.Baly and
Ms.Boakye for providing me with more
background information about the project. I
would also like to thank our parents for helping
us get on track. Without these people the
experiment would have gone wrong.
Our results from this experiment were somewhat exciting.
The hypothesis was correct. Some of the shell is still on
the egg. Some mistakes were that there was to much
vinegar in the jar. Another mistake was that we kept
the egg in the vinegar for more than 24 hours although
little bit of the shell was still on the egg. From this
experiment we learned that there is more than one way
to remove the shell off an egg.
