Yeah. Apparantly liquid Helium disobeys many laws of physics as it really does not experience friction with other surfaces. I wonder what color solid oxygen would be? I'm guessing that it would be a bluish semi-metallic like substance due to it's location on the periodic table and the fact that liquid oxygen is blue. (Liquid oxygen is really fun, but dangerous, to play with). I know that liquid O2 is attracted to a magnet, and that it will condense on the outside of a metal container holding liquid nitrogen.
I know that in recent years solid hydrogen was formed and it was found to be a metal. Solid helium may be a bit tough to come by as it melts at about a degree above absolute zero.
