Watch these wooden sponges wick up spilled oil 

Oil spills are messy and harmful to local ecosystems—just ask anyone on the Louisiana coast. So far, there’s no foolproof way to clean them up, and some methods—like burning the oil—can result in even more pollution. Now, researchers have come up with a potential solution: reusable, oil-wicking sponges made of wood that can absorb more than 40 times their weight in oil.
