Quick Kitchen Science - Bouncy Egg Experiment

By Jessica Newcomer, Publisher of Macaroni Kid York - www.york.macaronikid.com February 20, 2018

I have been finding quick and fun ways to bond with my daughter while adding an educational element. We have done several kitchen science experiments and it has been a lot of fun, for both her and I. One of our favorites was Bouncy Eggs! The Bouncy Egg experiment shows you how an acid can dissolve the calcium in the egg shell, leaving you with a just the inside sac of the egg. Plus, it's pretty fun bouncing the eggs after the experiment is over! 

What You Will Need:

  • Eggs
  • Clear glass jar or bowl with lid
  • Vinegar

How to Make Bouncy Eggs:

  1. Place eggs in a glass jar or deep glass bowl. (You can either use hard boiled eggs, or if you want the eggs to "splat" (messy science), you can use raw eggs.)
  2. Fill the jar or bowl with vinegar.
  3. Cover the container.
  4. After a few minutes you will be able to see the vinegar reacting with the egg shell and bubbles will form that cover the egg.
  5. After 24 hours replace the vinegar with new vinegar.
  6. After 3 days remove the eggs and have a bouncy good time! (Be careful if you used raw eggs, they will splat!)
