When I told the kids that they could remove the shell of an egg with out breaking it, well they wanted to see it happen with their own eyes.
I explained that the vinegar is an acid and will dissolve all of the calcium in the shell causing it to dissolve away, and all we would have left is the rubbery membrane below.
The bubbles that form on the shell and rise to the surface is carbon dioxide which results from the chemical reaction.
There are particles, too tiny to truly identify, they look like white fuzz or sediment. We noticed all these white spots on our egg.
On Tuesday morning, we noticed a lot of changes! There were cracks running all over the surface of the egg, and some more stuff floating in the water, definitely more white than brown.
I thought that we should change the vinegar out, to really finish the job.
By the time we came home that evening, a huge change!
No more brown and the consistency has changed dramatically, there is no more shell, it feels very much like a grape.
You can bounce it lightly on the table.
So eggciting! ( insert eye roll here...)It was very cool to shine a light through it.
