7th grade science project
Hello. I am doing an experiment to show which coffee brand or type stains teeth more. Can you tell me what i could use for teeth? Eggshells? Fake fingernails? Do you have suggestions for how I should alter my problem?
Egg shells work very well. I've never used fake finger nails before.
