Help me create a fake oil spill

How can I create a fake oil spill?
I'm going to a party on a beach, on a river. I would like to create a fake "oil spill" on the beach without actually polluting the river. So, a giant vat of black food coloring is right out. (Even if it's truly harmless, I don't want to get into screaming matches with folks about it.)
I have roughly 24 hours before I drive up. Any ideas?
