A week on and it was time to check out how our teeth 'egg'speriment was going.
To recap, we were investigating the effect of different drinks on our teeth. Due to the unavailability of teeth, we used egg shells instead.
We made sure our test was fair by using the same amount of liquid and the same size of eggshell in each case. We tested milk, coke, apple juice, blackcurrant, energy drink, water and vinegar.
The results were amazing, as you can see by the photos below.
We concluded, in the words of one child, that 'the drinks that are bad for our teeth are coke (because it made them turn brown and it would make our teeth rotten) but that milk is very good for our teeth because it's full of calcium'.
'This was a cool experiment,' said Timothy.
