Egg shell is similar in nature to the outside of our teeth. And since we are studying teeth at the moment we would like to find out how popular drinks affect the health of our teeth.
We will leave the egg shells for a couple of days and then record the result of the coke, vinegar, blackcurrent squash and water have on the egg shell.
We got our results today!
The coke stained the egg.
The blackcurrent juice stained the egg. It also caused a white mould to form.
The vinegar was very interesting. It dissolved the egg shell and it went to mush!
The water didn't change the nature of the egg shell at all. It stayed the same.
So in conclusion stick with water if you can to keep your teeth lovely and healthy!
