Fun Facts of Nitrogen
It makes up most of the air we breathe, but how much do you really know about this fascinating element?
Sure, we could make ice cream the boring, old-fashioned way with a big ol’ ice cream churn that scrapes and whips the cream full of air for 20 minutes or so, then we could store it in a -20 degree Fahrenheit freezer to harden for three or four hours and serve, eh, whenever... But we don’t think that’s "cool" enough. We choose to blast our ice cream with -321 degrees of liquid nitrogen to freeze it instantly and to-order so our ice cream is the smoothest, creamiest, and freshest frozen treat worldwide.
