Aerogel. Do you remember not so long ago when Aerogel was first introduced at NASA to insulate Mars rover and how cool would it be to own one? Now you can! Just look at these amazing facts: Aerogel is 99.8% air, it’s the world’s lightest solid, it’s world’s best insulator and can support over 1000x its weight… yep, you could place 2.5kg brick on a 2gram piece. It has melting point that is over 2000°F/1090°C. Nicknamed “Blue Smoke” due to its appearance. It really is hard to believe you are holding a solid and not, well, nothing. Aerogel is a great collectors’ item, gift, a unique and rare science display, or just something to amaze your friends.
