    Just read this article and figured I'd share it: http://arstechnica.com/science/news...-things-are-just-right-water-flows-freely.ars

    However I do have a question. The article never explained why helium, hydrogen, and other gasses were being blocked, they only explained how water was allowed through. Per the article:
    What about this particular way of assembling the graphite would cause helium and hydrogen to not leak out?
