Ok...Well I might change my initial idea on my method. Instead of using paint thinner, I'm going to use hairspray YAY!

Aim: To observe the permanency of permanent markers.

How permanent are permanent markers? What solvents (e.g., water, alcohol, vinegar, detergent solution) will remove the ink? Do different brands/types of markers produce the same results?

Hypothesis: The markers will react differently with each solvent or substance used.

Materials:

• Black permanent marker
  
• Water
  
• Rubbing alcohol
  
• Vinegar
• Hair Spray
  
• An A4 size piece of fabric, paper and plastic to test on
  
• 4 dropper

Method:

1. Collect the materials.
   
2. Starting with the fabric, lay it down in a landscape position.
3. Draw a line from one end to another.
4. Then draw 3 lines which bisect this line in even intervals, thus creating 4 small and even sections.
5. Wait for around 1 -15 minutes for the ink to seep in.
   
6. Apply a few drops of water onto one section, making sure that it is dropped on the horizontal black line.
7. Repeat this for the vinegar and rubbing alcohol.
8. Spray a small amount of hairspray that is approximately equivalent to the amount of the other 3 solvents applied to the other sections.
9. Observe.
10. Record observations in a table.
11. Repeat steps 2-11 for the remaining two materials.
12. Clean up.
13. Repeat experiment.

I hope this is okay.
