  1. THE INK OPERATION

  2. QUESTION: What solvents (tap water, Suave hair spray, rubbing alcohol, white vinegar, or Tide detergent) will remove ink?

  3. purpose • THE PORPOSE OF MY INVESTIGATION IS TO DETERMINE WHAT SOLVENT WILL REMOVE INK . This is important to know because if you have a stain of ink on your shirt, which solvent could you use to remove it without damaging the fabric.

  4. HYPOTHESIS • I hypothesize that Tide detergent will remove ink the best. We believe this because when we use detergent, it removes most of the stains to be found, on the cloth.

  5. PROCEDURES

  6. MATERIALS Toothbrush 5 droppers 1 bottle of Suave hair spray 5 spray bottles 1 bottle of rubbing alcohol 500 ml of Tide detergent 500 ml of white vinegar 500 ml of tap water A jar of ink 25 pieces of 4x4 cloth

  7. Variables • Manipulated variable • The solvents • Responding variable • The remainder of ink left on cloth • Constant variables • The amount of each solvent • Size of cloth • Rating scale • Toothbrush • Method of rubbing time

  8. directions • 1. Gather all materials • 2. Lay out 5 pieces of cloth of 4 cm x 4 cm • 3. Drop two drops of ink on each square of cloth • 4. Spray three sprays of each solvent on each square • 5.Scrub each solvent for 30 seconds with an old toothbrush • 6. Leave cloth pieces on a towel under the shade for 3 hours • 7. Rinse each cloth piece in water for 15 seconds • 8. Rate each cloth piece for the amount of ink remaining using a scale of 1 to 10 with 1 being all ink remaining and 10 being no ink remaining. RECORD. • 9. Repeat steps 2-8 for four more trials

  11. conclusion My hypothesis was correct. Tide detergent removes ink the best. Using a scale 1-10, the average for tap water was 2.4. The average for Suave hairspray was 2.8. For rubbing alcohol was 3.4. white vinegar was 2.2. Finally, Tide detergent was 5.2. If I had to do this experiment again, instead of rubbing, I would of just sprayed it and left it alone for three hours.
