Fluoride Egg Experiment
This experiment demonstrates the effectiveness of fluoride by showing how fluoride strengthens the shell of an egg.
1. Two eggs
2. Two large clear cups or beakers
4. School Fluoride Mouthrinse (or over the counter mouthrinse)
5. A pencil
Use the pencil to mark one of the eggs with an F. Soak the egg marked with an F in the fluoride rinse for at least 8 hours.
Place the fluoride soaked egg in a clear cup filled with vinegar. Place the untreated egg in another cup filled with vinegar.
Wait 4 minutes until the untreated egg begins to bubble. The breakdown in the surface of the egg is similar to the way acids in a person's mouth breakdown the surface of a tooth. The fluoridated egg is unaffected, the same way fluoridated teeth are unaffected by tooth decay.
