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 Place the egg in a tall glass, jar or a plastic cup and cover the egg with vinegar. 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. 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. 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 2 hours 12 hours 20 hours 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.

Acknowledgement page 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.
