Bouncy egg experiment

What to do with this activity?

Here's a science experiment that you can do in your kitchen. All you need is:

  • 1 raw egg
  • A clear glass or glass jug
  • Enough white vinegar to cover the egg


Leave the egg in vinegar for two days. Vinegar is an acid, so over time it will dissolve the calcium carbonate in the egg shell. Calcium is what makes the shell hard. 

Have a look at the Kidspot video above to see how you can gently bounce the egg when the shell is softened by the vinegar. 

Encourage your child to write about the experiment like a scientist. Name the experiment, write the date they did it, and what they found out.



  • Why am I doing this?

    Learning to write should be fun. It’s important that children know that writing is a fun and useful. By fitting it into everyday activities, like drawing, writing notes and birthday cards children will get used to holding a pencil and learning to write properly.

  • How can I do more?

    Encourage your child to write and draw  - on outdoor walls with chalk or in the sand at the beach. Give them picture mazes or puzzles to fill out – join the dot puzzles are great for their hand eye coordination.
