Fuzzy Egg Experiment

Benny bought us 101 Science Experiments book, and we thought of trying out the first one.

I had some quail eggs in the fridge.
So, I thought of using it instead of the chicken egg.

We put each egg in a separate glass.
The blue glass was filled with water.
The transparent one was filled with vinegar.

The interesting part was:
The egg which was dipped in the vinegar started to fuzz not long after it was in it.
The calcium carbonate which was in the egg shell dissolved, thereby creating a fizz.

The longer the egg stayed in the vinegar, the more fizz there was.
And after sometime, the brown part on the surface of the quail egg started to float.
Interesting.

We can see in the middle photo, the comparison between the egg in the vinegar and the one in the water.
The one in the water remained the same.
But the one in the vinegar, fizzed.

After some time, the egg in the vinegar has lost its brown spots, as you can see from the photo below.
It has a smooth skin now. hehehehe..
