The facts
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.
• This is high quality, cheap Aerogel
• This sample is great for fun science experiments and Collections
Safety
Silica based aerogels are not known to be toxic. Although, they are an irritant to the eyes, skin, 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. Keep out of reach of children
