Aerogel

The world's lightest known solid material!

Aerogel is one of the most impressive materials humans have created so far. 

Commonly called "frozen smoke", it is safe to touch, hydrophobic (repels water), and an outstanding insulator.

Due to its high porosity, NASA has even used aerogel to collect interstellar dust particles in outer space.
