The Power of fluoride!
This experiment shows the protection power of fluoride. Share this experiment with mom, dad, or another grown-up. A good idea for rainy days…
What you'll need:
1 bottle of fluoride rinse solution (available at most drug stores)

2 eggs
 in shells
1 bottle of white vinegar

3 containers
What to do:
Pour four inches of fluoride rinse solution into one of the containers.
Place one egg in the solution. Let it sit for five minutes. Remove the egg.
Pour four inches of vinegar into each of the remaining two containers.
Put the egg that has been treated with the fluoride into one container of vinegar and the untreated egg in the other container of vinegar.
What will happen?
One egg will start to bubble as the vinegar (an acid) starts to attack the minerals in the egg shell. Just like it does with your teeth! Which egg do you think will start to bubble?

Fluoride made the egg shell more resistant to the acid attack. Fluoride will also strengthen your tooth enamel and make it more resistant to tooth decay and cavities.

…Be sure to throw away the eggs after you're done
