Apparatus (Things you need): an egg, boiling vinegar, plastic cup
1. Put the near boiling vinegar in the plastic cup.
2. Put the egg in the vinegar.
3. Wait for 2 days for the shell to dissolve.
4. Then take the egg out carefully so it won't pop.
You can only see the membrane and the egg will get bouncy...
A bouncy egg!
The egg was bouncy because the shell dissolved.
