Can we obtain the Unobtainium?

This is a second video in my series on unobtainium, where we leave behind Avatar and Dune to have a look at what can real-life science offer us in terms of unobtainium. It's quite a lot, actually: there are room temperature superconductors, antimatter, helium-3, exotic matter and many other candidates for real-life unobtainium. Bear with me in this exploration of what stuff from science fiction is actually possible in science!
