We have carried out an experiment to find out what would happen to your teeth if you kept drinking certain liquids. We didn’t have any spare teeth so we used eggs as the shell is very similar to our teeth.
We put the eggs in five different liquids (coffee, water, milk, Pepsi and orange juice) and then left them for a week.
After a week we checked the eggs and some of the eggs had cracked. The egg in the orange juice was a bit mouldy and the top layer of the shell just brushed off completely.
The egg in the Pepsi went a bit browny black and a bit squidgy.
If we were going to try this again we might use hot chocolate, vinegar, squash and tea.
