Graphene Aerogel
— Lightest Solid Material Ever Developed

Because aerogels are porous they are ultra-light materials and this one is 100 times lighter than Polystyrene foam cups and can help clean up pollutants like toluene and crude oil (other oils as well) and other compounds like ethanol. Researchers are planning  to look at the materials ability for insulating and sound proofing in the future.

Previous records for lightest materials were 0.9 milligrams per cubic centimeter in 2011, 0.18 mg/cm3 in 2012, and now this material at 0.16 mg/cm3.
