More appealing than diamonds or gold, the world’s lightest solid matter the silica aerogel is truly a one-of-a-kind substance. Developed by NASA scientists, this solid consists of 99.8% air – yet can tolerate extreme heat and support over 1,000 times its own weight.
Aerogel goes by many names blue smoke , solid air, frozen smoke but it's comely called the world’s lightest known solid. Aerogel is also the word's most effective thermal insulator, 39 times better than the best fiberglass insulation.
NASA uses aerogel to trap space dust from comets aboard the Stardust spacecraft. Beforehand the dust would vaporize on impact with solids and pass through gases, but they can now be trapped in aerogel's tightly woven Nanostructure.
NASA also has used aerogel for thermal insulation in the Mars Rover and space suits. As well as in the US Navy seals suits to keep the divers safe and warm. aerogel is brittle but very strong under presser Aerogel is also extremely hydrophobic.
The silica aerogel is a perfect stock for many science lab experiments or science display. This is high quality, cheap affordable Aerogel it is great for fun science experiments and collections. Definitely a conversation starter piece.
WARNING: Safety Silica based aerogels are not known to be toxic. The silica aerogel particles are an irritant to the eyes, skin and respiratory tract. Small silica particles can potentially cause silicosis when inhaled. So it's recommended to wear protective gear including respiratory protection, gloves and safety goggles and most definitely keep it out of reach of children!
The Silica Aerogel The Worlds Lightest Solid Matter is evocative, to say the least, but that's why you're drawn to it in the first place.
