"Making Science Splat~tacular!"
Adam Thornton's

Supplies: 2 Uncooked Eggs, 2 Cups of Vinegar, 1 Tall Drinking Glass.

What happens: Place both eggs inside the tall drinking glass. Pour the vinegar over the
eggs and let them sit for at least 24 hours. The next day rinse the eggs under the faucet.
Use your fingers to make sure all the shell is removed. Hold your naked egg up to the light
and sneak a peek inside. What does it feel like?

Explanation: The vinegar is an acid that breaks down the calcium carbonate in the
eggshell. This chemical reaction reveals the invisible membrane hiding under the shell that
keeps the contents from oozing outside the egg.
