Big Question • What can remove permanent marker ink? Which agent can remove it the best? I want to test what can remove permanent ink.
Hypothesis I think that alcohol will remove the ink the best. I also believe that all of my selected agents will be able to remove the ink.
Interesting Facts • The vinegar did not remove the ink very well. • Flour actually did pretty good. • Alcohol did remove it the best, but smudged it a little. Although flour and dishwasher soap did not smudge at all. • Nail Polish remover had about the same effect as alcohol. • Flour and dishwasher soap needed more elbow grease.
Experiment • Materials: • Permanent Markers (I used Sharpie fine point and BiC fine point.) • Dishwasher soap (Palmolive) • Alcohol (rubbing alcohol 70%) • Nail Polish Remover • Vinegar • Flour (all-purpose) • Rags • White board • To complete this experiment: • Choose the first type of marker • Draw a line down the board • Take the first erasing agent, put some of it on the rag, and try to rub off the marker from the board • Repeat with all agents. • Then take the other type of marker, and do steps 1-4 Controlled Variables: I controlled the ink, because that only changed when I did the two types of markers. I also controlled the removing agents, switching them out with each marker.
Observations • Sharpie is more permanent than BiC, according to my experiment. • The BiC smeared more than the Sharpie when vinegar was put on. • Flour only works with water on the rag. • Alcohol leaves a faint blue line on Sharpie. • Nail polish leaves a faint blue line on Sharpie.
Analysis • Because alcohol and nail polish remover could take off all of the ink of BiC, it seems as though Sharpie is more permanent than BiC. • The flour by itself did not work, but with water, it did. When it was mixed with water, if made the flour more abrasive and could remove the ink.
Conclusion • My hypothesis was incorrect regarding the question can all the removing agents remove the ink. Vinegar could not. • My other hypothesis was correct. Alcohol was the best remover. • Permanent markers, are not truly permanent as soon as put on. Some solvents can remove the ink.
