Submission + - Sponge-Like “Swelling Glass” Absorbs (

MikeChino writes: A company called Absorbent Materials has created a new kind of “swelling glass” that can clean up contaminated groundwater by soaking up volatile molecules like a sponge. Dubbed Obsorb, the material can hold up to 8 times its weight in fuel, oil, and solvents without sucking up any of the water itself. Once the material is full it floats to the surface and the pollutants can be skimmed off.
