Transparent Egg Experiment: A Fascinating Science Lab Activity for Kids and Classrooms (video and PDF manual below)

This simple yet mind-blowing science experiment is perfect for kids in the classroom and at home. The Transparent Egg Experiment amazes with its visual transformation and teaches key science concepts like acids, bases, chemical reactions, and corrosion.

What Is the Transparent Egg Experiment?

This experiment involves soaking a raw egg in vinegar for several days to dissolve the eggshell, leaving behind a squishy, bouncy membrane that reveals the egg inside. It's often called the naked egg or bouncy egg experiment, and it’s a hit with both kids and adults!

Through this experiment, learners will:

• Understand how acids react with bases.

• Observe effervescence and corrosion in action.

• Learn about chemical changes and neutralisation reactions.

• Discover the importance of the eggshell and what lies beneath.

Materials Needed

• 1 raw egg

• White vinegar (or apple cider vinegar)

• A transparent cup or jar

• Cling film or a lid

• Optional: Food colouring (for fun visuals)

Step-by-Step Instructions

1. Gently place the raw egg into the jar.

2. Pour vinegar over the egg until fully submerged.

3. Cover the jar and leave it undisturbed.

4. Observe over 1–2 weeks. You’ll notice fizzing and bubbles at first!

5. After several days, gently rinse the egg to reveal a translucent membrane.

📌 Tip: Use clear vinegar for better visibility during the reaction.

What’s the Science Behind It?

The eggshell is made of calcium carbonate, a base. Vinegar contains acetic acid, which reacts with the shell to form:

• Carbon dioxide gas (seen as bubbles),

• Calcium acetate (a salt),

• And water.

This is a neutralisation reaction—a classic acid-base interaction!

Term	Meaning
Acid	A substance with a pH less than 7 (vinegar is acidic).
Base	A substance with a pH greater than 7 (eggshell = calcium carbonate).
Neutralisation	A reaction between an acid and a base to form a salt and water.
Corrosion	Gradual breakdown of materials by chemical reactions.
Effervescence	Bubbling due to gas release during a reaction.
