The Transparent Egg

MATERIALS:

1 raw chicken egg

Tall glass

Vinegar

DIRECTIONS:

Place the egg in a tall glass and cover the egg with vinegar.

After 24 hours, you will notice the shell is starting to dissolve. There will be some floating particles on top of the bowl. Carefully pour out the old vinegar, and replace it with fresh vinegar.

After 24 more hours have gone by, you will notice that the egg shell will have completely dissolved. Take it out of the bowl and observe.

WHAT HAPPENS:

The vinegar reacts with the egg shell which is made of calcium carbonate.  It breaks the chemical into its calcium and carbon dioxide. You see bubbles which are the carbon dioxide and the floaties in the vinegar are the calcium. 

GO SCIENCE!
