This project examines the hardness of different minerals as it relates to the use of using minerals as toothpaste alternatives. As teeth and glass have the same hardness, I used glass as a substitute for my teeth. I scratched the glass with minerals of different hardness, from soft to hard, to see which minerals could work best as toothpaste in case I ever run out of toothpaste in an emergency.

You are so creative. This is good and I look forward to the future. Great job!
Very creative and novel experiment. Goodluck on your future research, making your toothpaste!
You did a great job on this project. Your idea to use glass to mimic teeth was very creative! If I ever run out of toothpaste, I will contact you!!!
