Egg Science Experiment

I tried to do a science experiment with my kids. I was told that putting an egg in a glass of vinegar overnight would result in the egg being shell-less in the morning. My mom had some old vinegar she was going to throw out, so we decided to try the experiment.

The kids feeling the egg's shell to see that it's hard

The next morning we checked on the eggs to find
that the shells were still there, but they had become soft

Cutting the egg open, just for fun;
of course the kids wanted to feel the egg yolk

So even though in my mind, the experiment did not go as planned because the shell was still there, the kids liked that it turned from hard to soft. I blame this on the old vinegar. We may have to try it again someday.
