This is Aerogel

Quick Facts
It is 99.8% Air

Is 1,000 times less dense than glass

Aerogel withstands heat up to 1,400 degrees Celsius (2,552 degrees Fahrenheit).

Aerogel is mable alternative to sound insulation materials

A piece 2.5mm (1 inch) thick will protect a human from the heat of a blow torch

A block of aerogel as large as a human may weigh less than half a kilogram (or less than a pound), yet support of about 454 kilograms, or 1,000 pounds.

Aerogel starts as a silica dioxide gel, similar to the gelatin dessert one might make at home. Then the liquid in the gel is removed without collapsing the gel (normal evapor- ation causes the gel to collapse). Through a process called supercritical drying, the material does not collapse but retains its original size and shape.
