Science can be a lot of fun. Making a bouncy egg is fun, especially since we all have experienced what happens when you drop an egg on the floor.
Bouncy Egg Experiment

In our original experiment, we put an egg in a jar of vinegar – on the left, and an egg in a jar of water – on the right. My girls noticed the bubbles around the vinegar egg. We used small jars so that we could screw the lids on tight to avoid a smell. Then we put them on the counter and waited. And waited. And then to our disappointment forgot.
What Happens When You Forget
Everything I read said to leave them for 72 hours. We left ours for at least 100. Yes, much longer. But we held out hope. Hope that it was still going to work, that there was going to be a bounce.
We took our vinegar egg out. It was bigger than the regular (water) egg. And missing a crucial part of an egg – the shell.
Holding the egg seemed quite odd, it was rubbery, and tougher than it seemed. We all handled it, and it didn’t break. It did however fail the bounce test. My kids had a good laugh at it, and then we checked out of the membrane.
What Happens When You Remember
I redid the experiment with much better results. I set an alarm on my phone this time, labeled it so I would know why it was going off.
When left in the vinegar for only 72 hours you had to rub then rinse the shell off of it. I used a slow flow of water, just in case.
We all handled this egg as well, and it didn’t break. And then came the bounce test. It worked! It worked, I bounced it a number of times, before it broke.
I figured out how to use my camera for video just so you could how it bounces:
