A research team headed by Professor Gao Chao have developed ultra-light aerogel – it breaks the record of the world’s lightest material with surprising flexibility and oil-absorption. This progress is published in the “Research Highlights” column in Nature. Aerogel is the lightest substance recorded by Guinness Book of World Records. It gets its name due to its internal pores filled with air. In 1931, American scientist Kistler first produced aerogel with silicon dioxide, and nicknamed it “frozen smoke”. In 2011, HRL Laboratory, University of California Irvine, and California Institute of Technology collaborated in developing nickel aerogel with a density of 0.9 mg/cubic centimeter, the record lightest material at that time. It couldn’t even cause deformation on dandelion flower fluffs. The picture of nickel aerogel was selected as one of the top ten pictures of Nature. Deeply impressed by the picture, Prof. Gao Chao asked himself: is it possible to challenge the limit with new material?
First there was aerogel. Developed in 1931, "frozen smoke" held the title for world's lightest material for more than eighty years. And at 96 percent air, its easy to see why. Last year aerographite jumped into the number one spot. At six times lighter than air, one cubic centimeter of the stuff weighs just 0.2 milligram. Aerographite was heralded with much fanfare when its discovery was first documented, but its reign was to be a short one. This month, a team of scientists at China's Zhejiang University went after — and broke — the lightness record set by aerographite. Their discovery is a spongy substance made from freeze-dried carbon. They've dubbed it graphene aerogel, and it weighs in at a tiny 0.16 milligram per cubic centimeter. That's only twice as dense as hydrogen.

From the moment i saw areogel i wanted a .... box of it to play with.
Graphine version is only a fraction lighter than the previous stuff, but if its better in anyway i must have it!
imagine getting a massive block of this, or perhaps several and doing some juggling on godzilla scale
