what things can I compare and I have to prove SCIENTIFIC EVIDENCE
I was going to use different brands of toothpaste but idk how to show one is better ;(
I WILL GIFT SOMEONE IF THEY GIVE ME A LEGIT GOOD IDEA
Comments
compare like laundry detergents or soaps or something
you can find facts for toothpaste brands online
you could also just compare the densities of salt water vs fresh water, i think its like u put a boiled egg in each one and in the salt water it will float bc of the density or something?? LOL idk
