Well there's my new goal in life - to own every one of those substances. I wonder what would happen if you mixed them all together?
It also seeps right through otherwise solid materials because its complete lack of friction allows it to flow through otherwise invisible holes that would not allow regular helium (or water for that matter) to flow through.

10. The Darkest Substance Known to Man
What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black. Scientists are really excited about the potential applications of the substance; since virtually no light is “wasted”, it would be used to improve optical tools like telescopes, and even be used to make nearly 100% efficient solar collectors.

A thread like this should be taught in every public school and shown as a feature on all network newscasts. The world of science, seen close up and far away, opens the mind to even more possibility. I'm interested in the world's most powerful microscopes and telescopes - the range of data on the visual as well as theoretical limits.
