Answers:    I think your experiment will necessitate to be more controlled.
you have to breed sure that you scribble equal amounts on both plastic sheet, i.e. hard to do. An alternative might be to spray ink, muddy hose down, onto the sheets, say 20 squirts respectively, that way, it will be easier to do a equal comparison.

You might try several different types of stains - mustard, grass, ink, etc. Whatever you choose practice at home first. You don't want any surprises when you put together your presentation.
