Is graphene aerogel lighter than air? I thought it _was_ mostly air, which is why its so light.

About 7 times lighter than air, AFAIK.

https://en.wikipedia.org//wiki/Aerographene It is approximately 7.5 times less dense than air. Note that the cited density does not include the weight of the air incorporated in the structure: it does not float in air.
