Solid Oxygen

Google tells me that the freezing point of oxygen is -222.65 degrees Celsius. For you Yanks out there, that''s colder than you could possibly imagine.

Resist everyone

Drop it into a well that''s been cooled to absolute zero.

I have seen liquid Oxygen, but not solid. Liquid is a sweet blue colour. What about solid?

Do not meddle in the affairs of moderators, for they are subtle and quick to anger.

Absolute Zero Quick Sheet
Noting that AZ is around -270C. And Oxygen freezes at -220C. I'd say it's a safe guess few people in the world have seen 'solid oxygen' in real life.

It's light blue in colour too, if I remember correctly. We have used solid O2 at uni, because of it's paramagnetic properties (not by cooling it down, but through pressure, btw). At higher pressures, solid oxygen actually exhibits very interesting changes. You'll have individual atoms bonding together through pressures, first forming sporadic O3 (an almost black colour in solid form), later O4 (blood red in colour), and finally becoming a superconductor (recently discovered).
