Made of sunflower pollen, the sponge is hydrophobic - it repels water - thanks to a coat of natural fatty acid on the sponge. In lab experiments, the scientists showed the sponge s ability to absorb oil contaminants of various densities, such as gasoline and motor oil, at a rate comparable to that of commercial oil absorbents.
