Egg and Vinegar Experiment.


So, I’ll admit.. I’m not really the mom to do amazing projects all the time. I try to remember to do cool projects, it just doesn’t always happen. I am getting better about fitting them in though!


I read about this great egg and vinegar experiment and seemed like the perfect little project for us. Simple, not a lot of steps, with a great result. Sold!


What You’ll Need for the Egg and Vinegar Experiment


  • vinegar {we used white vinegar}
  • egg{s}
  • dish or bowl

How the Egg and Vinegar Experiment Works


We did this experiment with four eggs total. Two eggs we boiled first and two eggs we left raw, to see if there was a difference between the two. Jorryn’s theory was that the hard boiled eggs would be bouncier.


Put your eggs in a bowl, then cover them in vinegar. Because vinegar contains acetic acid, it reacts to the calcium in the eggshell. After three or four days, the egg shell will be completely dissolved.

These are the hard boiled eggs after putting them in the vinegar.

These are the raw eggs after being in the vinegar. They remained pretty foamy the entire time!

This is the raw egg after four days in vinegar. It felt like a bouncy ball! The hard boiled eggs looked exactly like hard boiled eggs after you take the shell off of them.

It didn’t last as long as we hoped! The raw egg burst and went down the sink after only a few bounces. Granted, those bounces were from several inches up! Jorryn and Zane were equal parts disappointed and thrilled when it burst.

The hard boiled egg smashed just like a regular hard boiled egg. Jorryn was able to juggle it for a few minutes at least! πŸ™‚Β He was pretty surprised to find that the raw eggs were bouncier than the hard boiled!

If you are looking for a simple project that will delight your kids, I would definitely recommend trying this egg and vinegar experiment!

    I’m adding this to our list of try this! Seems easy enough. Patience is not our strong suit though.

      Haha.. we are the same, Stephanie! Even though we usually like “quick” things — Jorryn did enjoy watching the different stages of the project and checking it everyday to see the progress of the shell “melting” so in the end it didn’t seem like waiting at all! Hope you enjoy it, too! πŸ™‚

    interesting….I was home schooled for 1st grade and my mom had these books FULL of projects like these. I wonder if she still has them….

    I vaguely recall as a kid I remember doing something with the boiled egg yolk by putting it in the fridge to make Amber. Does anyone else recall this and if there was any other things or steps to it?
