This carbon aerogel has a density of 0.16 milligrams per cubic centimeter, according to scientist Gao Chou of China's Zhejiang University. Ghou combined graphene and carbon nanotubes to develop the material. The highly flexible material can also conduct electricity, and with an internal structure that is 99% free space, it can be compressed into a fraction of its size. The aerogel can absorb up to 900 times its own body weight in liquid, making it a breakthrough material for applications like cleaning up oil spills.

Nanotubes are highly toxic materials, using them to clean up oil spills could be worse than the spill itself. The potential to enter the lungs and cause cellular damage and eventually cancer is unprecedented. I can hardly believe these researchers are not using gloves and masks to handle these objects.

This very porous material itself is 1/6th the density of air, but that is if you evacuate the air from it.

Hmmm, if it was 1/6 the density of air, wouldn't it rise in air?
