Naked Egg Science ExperimentDid you know that you could make an egg bounce? Experiment with these fun bouncing Easter eggs to discover how it works! This simple science experiment is super fun to do and an affordable learning project to do with the kids!

Bouncing Easter Eggs-Naked Rubber Egg Science Experiment:

What you need:

  • Clear Wide Mouth Containers
  • Raw Eggs
  • White Vinegar
  • Food Dye if Desired


This project is super easy to do, but it does require some time and patience. It can take anywhere from 3-7 days for your eggs to lose their shells!Naked Egg Science Experiment

To start your project you will simply place your egg into a clear container and cover with vinegar. This will need to sit for 24 hours. During this time have kids make observations – Are the eggs floating? Sinking? Do you see bubbles?Naked Egg Science Experiment

After 24 hours drain your eggs and replace with clean vinegar. If you haven’t already you are going to want to make sure that the clear container you are using has a wide mouth as the eggs will expand as they absorb the vinegar. Be very careful during this process to not poke a hole into your egg shells.Naked Egg Science Experiment

Let your eggs sit for another 3-7 days.

In a couple of days the shell should be completely gone! Gently rinse the eggs with warm water and explore!Naked Egg Science Experiment

You’ve successfully made an egg without a shell. Now to see if it can BOUNCE!

How Bouncy Easter Eggs Work:

The shell of an egg is made of calcium carbonate. When you place the egg into the vinegar, you will see bubbles. This is the chemical reaction of the acid in the vinegar reacting with the calcium carbonate to produce carbon dioxide.Naked Egg Science Experiment

You will also notice that the egg gets larger as it sits in the vinegar. That is because some of the vinegar is absorbed in the egg through its semi-permeable membrane!Naked Egg Science Experiment

Simple and fun science!
