Supplies Needed:

2 hard boiled eggs

1 bottle of dark soda

1 cooled cup of coffee

2 plastic cups

Procedure:

  1. Put 1 egg in each cup
  2. Label cup 1- SODA
  3. Label cup 2- COFFEE
  4. Pour dark soda over egg in cup 1 to cover entire egg
  5. Pour cooled coffee over egg in cup 2 to cover entire egg
  6. Let eggs sit over night (at least 8 hours)

Question: What do you think will happen to the egg?

Imagine your teeth being these eggs.  Soft drinks and coffee affected the egg shell, just like they would affect our teeth.  Try taking a toothbrush and brush the egg like you would brush your own teeth.  Do you notices any changes to the egg?  If you brush your teeth at least 2 times a day, you teeth will be just as clean and white as the egg was in the beginning.

Remember to:

Brush your teeth at least 2 times each day to keep them protected, strong, and white!
