Mom to Posh Lil Divas and I thought that Lillie would enjoy it.
What you will need:
2 brown eggs
2 white eggs
4 clear glasses to watch the reaction happen.
Gently place 1 egg in each glass. Add vinegar to 1 white egg glass and to 1 brown egg glass. Add water to 1 white egg glass and 1 brown egg glass. I put in enough water or vinegar to cover the egg. Then we watched. Within minutes we saw bubble forming and coming off the eggs that were placed in the vinegar. (see the little lines in the vinegar above the egg?)
internet that: "An egg floats due to the release of bubbles of Carbon Dioxide gas from the reaction of the vinegar with the Calcium Carbonate of the eggshell. The bubbles cling to the shell giving it lift."
By the end of the day, we saw the layers of the egg coming off of the egg.
On Day 3, we compared the eggs in water and vinegar and noticed that the size of the bubbles were bigger and more of the eggshell layers were coming off. We also noticed that the eggs in vinegar seemed bigger than the ones in water.
There was basically no change to the eggs between day 3 and 9.Finally, by day 9 the final layers were starting to disappear.
After a week, I was surprised that all of the shell wasn't gone, like I had seen in the Mom to Posh lil divas post. So, I looked up other egg experiments on the Internet. I found that on day 2, I was suppose to dumped out the vinegar and rinsed the vinegar eggs in water. After rinsing them, place them back into glasses of vinegar. This speeds up the process of the vinegar dissolving the shell.
So, I rinsed them on day 11 to remove the final shell.
It was a great experiment and I can't wait to try it again.
