and these were the solvents used

morning fresf detergent

home brand white vinegar

golden canola oil

cutx nail polish remover and

normal water

and for your entertainment, this is what it looked like in the cup during the experiment

i've done my experiment but since there are too many pictures to upload, i'll just tlk about them..
so basically, the water, vinegar and oil had little effect on the permanent marker probably because they are not strong enough. they have some effect as it thickened or got rid of it a little bit but it wasnt very much
the detergent was better than those three and removed a bit more of the mark but the whole fabric just turned green (coz i used green detergent) so yeah....
the best results came from the nail polish remover. i think it worked because it is not one of those everyday stuff like water, oil, detergent and vinegar so has more chemicals which got rid of the mark
im quite happy with the results as it showed at least something that could get rid of the mark

Method for the 1st experiment (marking the objects)

1. Prepare objects with different surfaces such as plastic, glass and cotton
2. Get different 3 coloured sharpies and permanent markers of other brands and mark each surface with a one centimetre mark from each marker.
3. Wait for a period of 4 weeks.
4. Check how permanent the each marker is by noting the change of the mark and scrubbing.

Method for 2nd experiment:

1. Pour 20mL of each solvent into each container.
2. Mark a piece of cloth with a type of permanent marker.
3. Leave it in overnight.
4. Take it out of the solvent and scrub it.
5. Note any colour changes and record the results.

my beautiful climatic graph...

yea here it is...

i did two separate graphs and then put them together on paint since im hopeless at photoshop and as katherine pointed out, there isnt suppose to be a 'c' in between the 'a' and 't' in climatic

today i bought a new pack of sharpies for my experiment. i was trying them out but now i have a headache... permanent markers do not smell very nice TT
anyways i went on the internet to find out more about permanent markers and while researching i also (unfortuantely) found out the actual answer for my experiment- no permanent markers are not permanent
according to ehow, for a permanent markers to be permanent, it only has to satisfy two qualifications:
1. it dyes or pigments and
2. it must adhere to most surfaces and be water-resistant

i did some research on permanent markers and i found that it is generally water resistant as it contains solvents such as xylene, toluene or alcohol but can be removed with denatured alcohol, acetone, steam
so for my experiment i'll also try using nail polish remover which contains acetone to get rid of the mark...
