After a previous project, I knew I could create patterns with the oil residue off silly string. Thus I purchased a can and sprayed it all over a piece of paper and let it set. When I returned a few hours later as I predicted it had left oil stains on the paper- that looked just like the oil spills in the ocean that we have to face today.
I really like the patterns created and feel they are an amazing representation of oil spills. I feel if I develop this further It has great potential for patterns.
