MY SCIENCE PROJECT

We were testing which liquid out of coke, water, vinegar and orange juice stains your teeth the most. We used egg shells for teeth and put them in these four liquids for 24 hours.

I predicted that the coke would stain the most and that water wouldn't stain at all.

Here are my results:

before

after

I found out that coke left the worst stain, vinegar was bad but coke was definitely the worst. Orange juice was 3rd but it turned out worse than I thought. Water was the best cause it didn't stain at all. I have learnt from this that the best thing to drink is WATER!
