This is easily one of the best experiments we've ever done. I pinned it months ago and was dying to try it with the kids but I'm glad we waited until summertime because the eggs moved around a lot and the kids had fun watching them.
This experiment is super simple and the results are amazing. All you need is:
vinegar
raw egg(s)
a jar or container
| As soon as we put the eggs in the vinegar the shells bubbled up. |
All you do is put the eggs in the jar, fill the jar with vinegar, and wait. The vinegar will completely dissolve the egg shells and thicken the membrane surrounding the egg, leaving you with clear, rubbery eggs.
| A few hours later the eggs began to float up to the top, then drop back down to the bottom. |
The site where I found the experiment advised me to change the vinegar after 24 hours, then wait another 24 hours for the end result. We did change the vinegar the 2nd day, but our eggs were ready after about 27 hours. While I was changing the vinegar on the 2nd day, I carefully rinsed the eggs which I think helped speed the process.
| By the end of the first day both eggs were at the top of the jar and very bubbly. |
The end result: By day two our egg shells were completely gone. Leaving us with still raw but rubbery eggs. When we held the eggs up to the light we could see the yolks floating around inside.
One word of caution. The eggs are still raw and right after we took them out we wound up dropping and breaking both eggs. Be careful when handling the eggs and use more than one egg in the experiment. That way you'll have some back ups.
