                 Abstract
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.
                Introduction
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
 it.
                    Hypothesis
If the egg is in the vinegar then the shell will
  dissolve with still a little bit of the egg shell left.
                        Procedure
1.   Place the egg in a tall glass, jar or a plastic cup and cover the egg with
     vinegar.
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
     correctly.
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.
               Materials
 Raw  egg
 Glass Jar or Plastic Jar
 Vinegar
 notebook paper
                     Observation
   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.

                  Data
Time (in hours)     Observation
1 hour              Bubble are starting to form.


2 hours             Bubbles are surrounding the egg inside the
                    jar.

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.
               Data analysis
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
  almost dissolved.

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.

                    Conclusion
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.
