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

Ferro Fluid , A Magic Liquid ?

Well , First time i know about this liquid 'cause i've watched discovery channel . Why it makes me so interested ? the liquid can move when a magnet nearby it . In Wiki the liquid called Ferro Fluid. 
A fluid in which fine particles of iron, magnetite or cobalt are suspended, typically in an oil. A ferrofluid is superparamagnetic and can create liquid seals held in position by magnetic fields .

NASA has experimented using ferrofluids in a closed loop as the basis for a spacecraft's attitude control system. A magnetic field is applied to a loop of ferrofluid to change the angular momentum and influence the rotation of the spacecraft. This Liquid Magnet also can be used for cancer detection , used to form liquid seals around the spinning drive shafts in hard disks, etc . .

. . or you can use this liquid to give a pranks , like Freak Encountered  do . . :) i used to watched that episode and get more interested in this liquid :)
