3D print your own bikini, and clean up the ocean

OK I am not so sure about the cleaning bit.  Anyways, the authors created a material that repels water but sucks up oil and chemicals.  And used a 3D printer to print out a custom bikini with the material.  I am more impressed with the bikini printout than the material.
