assistant
Nanotubes, often known as Carbon Nanotubes, are light, strong shapes made of Carbon atoms.  Nanotubes are shaped like tiny straws with walls as thin as one carbon atom.  They are considered as the strongest of any material known to man.  Nanotubes have many practical uses, one of which is to make the darkest black paint.
