Why did we choose liquid nitrogen for our ice cream?

Liquid nitrogen is cold, very very cold. It boils immediately as soon as it makes contact with anything that is warmer than itself. The technical term for this is Leidenfrost effect, but enough with that, what’s important is the faster you freeze ice cream, the smaller the ice crystals can be, and thus the smoother the texture.  Oh, one more thing, we love our earth so we want to make sure we are not exhausting our earth’s resources, just so you know, nitrogen is about 78% of our atmosphere, so no worries there!
