Eggsperimenting

To learn about the importance of dental hygiene the boys undertook some eggsperiments. For the first of our experiments we soaked hard boiled eggs in different liquids- orange juice, apple juice, coke, water. After 24 hours we took the eggs out of the liquids. The only egg that wasn't stained was the egg soaked in water. We had a look at the eggs and then we brushed them with toothpaste and water. There was a massive difference and it proved that it is very important to brush your teeth at least twice a day.

The boys undertook another experiment by soaking a hard boiled egg in a jar of vinegar. This experiment showed how acid interacts with calcium to cause tooth decay.
