## Is there anything lighter than air?

The answer is yes! 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”.

## How hot can aerogel get?

Monolithic silica aerogels remain generally in tact until about 650°C at which point they begin to sinter (densify). At hotter temperatures silica aerogels will eventually melt. Composite aerogel blankets such as Aspen Aerogels’ Pyrogel® XTE blanket can be used up to temperatures of about 650°C.
