Teach your child how brushing your teeth keeps surfaces clean.

- Hardboiled egg with white shell
- A glass

What To Do:
- Together with your child, carefully place a hardboiled egg into the glass.
- Pour the cola into the glass, making sure that the egg is fully submerged. Leave it overnight.
- The next day, have your child take the egg out of the glass with a ladle or spoon. Talk about what she sees. Ask her, “What happened?” “Why do you think it turned this color?”
