You want to test new techniques for cleaning up ocean oil spills, but don't want to dump oil into the water -- what do you do? If you're the Norweigian Clean Seas Association for Operating Companies, you use popcorn instead. It turns out that popcorn, once it absorbs water, forms an emulsion that mimics the behavior of oil in ocean currents... and any bits that don't get cleaned up in the test provide a tasty snack for wildlife.
