The Frozen Smoke , Aerogel

Smoke but we can hold it ? what kind of sorcery is this ?! probably you've not heard about this before :)

Created by Samuel Stephen Kirstler in 1931 as a result of a bet with Charles Learned over who could replace the liquid in "jellies" with gas without causing shrinkage.

Aerogel ,the Frozen Smoke is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity.

Did you know ? Aerogel is the world's lowest density solid,clocking in at 96% air . So , if you hold a small piece in your hand , it's practically impossible to either see or feel , but if you poke it , it's like styrofoam .

from information i've read , it supports up to 4000 times its own weight and can withstand a direct blast from 2 pounds of dynamite !!! . wow
