 THE PURPOSE OF THIS PROJECT IS TO DETERMINE WHAT SOLVENTS WILL REMOVE INK. THIS IS IMPORTANT TO KNOW BECAUSE CLOTHES ARE EXPENSIVE. IF YOU GET INK ON THEM, YOU WOULD WANT TO KNOW HOW TO GET IT OUT.

WE HYPOTHESIZE THAT VINEGER WILL REMOVE INK. WE BELIEVE THIS BECAUSE FOR MANY YEARS IT WAS USED FOR CLEANING THINGS.
