Graphalloy components can withstand temperature fluctuations ranging from cryogenic to 1000F and are dimensionally stable even when submerged or under load.
About three stories high and only half completed, the magnet loomed like a monster made of giant blocks of metal and a confusing mess of cryogenic coolant pipes.
This is not to be confused with cryogenics, which is basically just the study of things at very low temperatures and probably wouldn't make for that interesting of a video!
Well, because you were such a go-getter, you decided to hold onto the absolute zero metal as long as you could, and as a result, you've got fourth-degree cryogenic burns on your hand.
