In an effort to provide a cheap, reusable method to clean up water after oil and chemical spills, Tanmay Das and Debasish Haldar of the Indian Institute of Science Education & Research, Kolkata, coated a polystyrene sponge with a compound that allows it to absorb a wide range of oil and organic solvents but not water (ACS Omega 2017, DOI: 10.1021/acsomega.7b01379). Watch this video to see the oil-mopping sponge in action.

Well, polystyrene is common used penoplasty... but coated with a compound that besides hydrophobic cyclohexyl groups contains picramide and hexogen-like structure :O
