Aerogel
Beside this, are there any solids lighter than air?
Graphene aerogel is seven times lighter than air, can balance on a blade of grass. Chinese material scientists have created the world's lightest material: A graphene aerogel that is seven times lighter than air, and 12% lighter than the previous record holder (aerographite).
Beside above, what object is lighter than air? Since air is made up of certain elements (mostly nitrogen and oxygen), any gaseous elements or molecules that are lighter than these elements—such as helium, hydrogen, or methane—will be “lighter than air”. This is why when you fill a balloon with helium, it floats!
Moreover, which is the lightest metal on earth?
magnesium
What is lighter than air but can never be lifted?
A bubble.

Are aerogels expensive?
Even though producing more aerogel at a time would bring its price down, the process and materials alone come with a high price tag of about $1.00 per cubic centimeter. At about $23,000 per pound, aerogel is currently more expensive than gold [source: NASA JPL, FAQs]!Does aerographite float?
However this space is filled with air, and precisely because it is filled with air it doesn't float. But in the atmosphere, the air fills the immense empty space. The effective volume of air displaced by aerographite now takes up only the volume of the constituent nanotubes of aerographite, which is extremely small.Can Aerogel stop a bullet?
Strong Enough To Stop a Bullet in its TrackTo collect these delicate particles, each smaller than a grain of sand, aerogel will gradually slow them to a stop without damaging them or altering their shape and chemical composition.
Can a solid be less dense than a gas?
No. The molecules in a gas are about 1000 times as far apart as the molecules or atoms in a solid. In order for a solid to be less dense than a gas, the molecules or atoms of the solid would have to weigh less than 1/1000 as much as the molecules of the gas. No solid material that is not a foam is less dense than air.Is hydrogen lighter than air or heavier?
With air being equal to 1, gases with vapor densities below 1 are then lighter than air and gases with vapor densities greater than 1 are heavier than air.| Name | Vapor Density (Air=1) |
|---|---|
| Hydrogen | 0.1 |
| Methane | 0.6 |
| Nitrogen | ~1.0 |
Does solid helium float?
The answer is no. Solid helium has a density of 0.214±0.006 g/cc at 1.15 K and 66 atm; the projected density at 0 K and 25 bar (2.5 MPa) is 0.187±0.009 g/cc. At higher temperatures, helium will solidify with sufficient pressure. At room temperature, this requires about 114,000 atmospheres.How do you make aerographite?
Aerographite is produced by chemical vapor deposition, using a ZnO template. The template consists of micron-thick rods, often in the shape of multipods, that can be synthesized by mixing comparable amounts of Zn and polyvinyl butyral powders and heating the mixture at 900 °C.What is the strongest metal in the world?
