Have you ever bounced an egg?

We have!

And you can too...

Materials:

• 1 raw egg(in the shell)
• drinking glass
• vinegar

1. Carefully set the egg in the bottom of the glass.

2. Fill the glass with vinegar and let it sit for at least 15 hours.

3. Remove the egg and drop it (we used an empty baking pan).

The egg's shell will feel rubbery and won't break because the acid in the vinegar breaks down the calcium carbonate that makes eggs' shells hard.
