1. INK SPLATTER

2. What solvents will remove ink?

3. PURPOSE
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, then you would want to know how to get it out.

4. Hypothesis
We hypothesize that vinegar will remove ink the best. We believe this because for many years it was used for cleaning.

5. Procedure

6. Materials
Dropper Ink 20 mL of water 20 mL of Wisk detergent 20 mL of alcohol 20 mL of vinegar 5 spray bottles 5 rags 5 labels 5 – 5 cm x 5 cm fabric squares 20 mL of hair spray 5 trays

7. V ariables Manipulated: solvents Responding: the amount of ink removed
Controlled: The fabric, amount of solvents , the amount of ink, rag , dropper method of rubbing stains

8. Step by step directions
Put 5 pieces of fabric on a table .
Place ink in dropper.
Drop 5 drops on each fabric square .
Label fabric squares A , B, C, D, and E.
Label spray bottles A , B, C, D, and E.
Put water in A , vinegar in B, alcohol in C, detergent in D, and hair spray in E.
Spray 5 squirts of each solvents on each piece of cloth.
Try to rub ink out with a rag. Rub each piece for 30 seconds.
Record the degree the stain is removed using a rating scale of 0 to 10 with 0 being no change and 10 being completely removed.
Repeat 1-9 for four more trials.

12. Conclusion
Our hypothesis was incorrect. We found out detergent removes ink the best. The average ink removal rate of water was 5.8, vinegar’s average was 5.4, detergent’s average was 6.6, and alcohol’s average was If we had to do this again, we would put 5 drops of ink on the cloth and put the each fabric piece in solvent in a container with a lid. We could shake for 1 minute . We would do this to see if the results would be the same as ours.
