Bouncing Eggs!!
Materials:

Procedure:
Fill a glass with vinegar and let an egg soak in it. The next day notice that the egg has turned into a rubber ball. You can now bounce it!!
Explanation:
The eggshell is made of calcium carbonate which makes it hard. The calcium carbonate will absorb the acid of the vinegar and become carbon dioxide gas, which will go into the air.
