Vinegar is an acid. Eggshells are made of calcium carbonate. If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. What is left is the soft tissue that lined the inside of the eggshell. It will bounce!
Science Experiment Idea: Make three bouncing eggs. Soak one egg in vinegar for 24 hours (1 day), one egg for 48 hours (2 days) and one egg for 72 hours (3 days). How do the eggs look when done soaking? How does each egg behave when you try to bounce it? Hint: BOUNCE OUTSIDE!
