It's almost as light as air, yet it can withstand a direct dynamite blast.
And while it looks like frozen smoke, it can withstand a direct blowtorch
flame of over 1300 degrees F (704 degrees Celsius).
Its name is aerogel, and although it was discovered over 75 years ago, it
may just be the material that will shape the next century.
