From that video it looks like just normal LN2..not LHe
Im calling it a bug and someone who doesnt know chemistry..as honda said Lhe doesnt boil like that. (Lhe boils at a much lower temp then Ln2)
LHe would freeze over the board way to fast..just read what chew did and how many issues they had when they got the record..
but if legit (in anyway) well though as that a very good chip.
