…and the results are in! As many of the children predicted, Coca-Cola had an adverse effect on the egg-shell (our teeth in this investigation) with a large amount of discolouration occurring. However, orange juice was the drink that appeared to damage the egg shell the most.

As for the milk… it smelt a lot after a whole week but didn’t have much of an impact on the egg shell. We therefore concluded that Coca-Cola and orange juice were the worst drinks for tooth decay, and that water was the safest choice.
