Ink Splatter

What solvents will remove INK?

PurposeThe 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 in a

matter of time.

HypothesisWe hypothesize that vinegar will remove ink the best. We believe this because for many years, vinegar was used for cleaning things.

Procedure

MaterialsInkA dropper20 mL of each solvent: vinegar, alcohol,

detergent, hairspray, water5 spray bottles5 rags5 labels5 - 5 cm by 5cm fabric squares5 trays

VariablesManipulated/Independent: solvents

Responding/Dependent: the amount of ink removed

Constant/Controlled: the fabric type and size, amount of solvents, the amount of ink, rag, dropper, and method of rubbing stain

Directions 1. Put 5 pieces of 5 cm by 5 cm fabric

on a table 2. Place ink in dropper 3. Drop 5 drops on each fabric square 4. Label fabric squares A, B, C, D, and E 5. Label spray bottles A, B ,C ,D, and E

Directions Continued 6. Put water in A, vinegar in B, alcohol in C, detergent in D and hair spray in E. 7. Spray 5 squirts of each solvents on each piece of cloth. 8. Try to rub ink out with a rag. Rub each piece for 30 seconds. 9. Record the degree the stain is removed using a rating scale of 0 to 10 with 0 being no change and 10 being completely gone

10. Repeat 1-9 for 4 more trials

THIS IS A PICTURE OF TRIAL TWO

ConclusionOur hypothesis was incorrect. We found out that detergent removes ink the best.

The average ink removal rate of water was 5.8, vinegar was5.4, hair spray was 5.4, detergent was 6.6 and alcohol was

4.0. If I were to change the investigation, I would rather soak the fabric in the

solvent instead of spraying it, or I would let the ink dry before we spray it. This

make yield different results.
