Scientists will change the world. They discover a material for the 21st century could protect your home against bomb blasts, mop up oil spillages and even help man to fly to Mars.
A 2.5 kg brick is supported by a piece of aerogel weighing only 2.38 grams.
Aerogel, one of the world’s lightest solids, can withstand a direct blast of 1kg of dynamite and protect against heat from a blowtorch at more than 1,300C.
According with Wikipedia Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as an insulator. It is nicknamed frozen smoke, solid smoke or blue smoke due to its semi-transparent nature and the way light scatters in the material; however, it feels like expanded polystyrene (Styrofoam) to the touch.
