Vn + Cf + Mw. A chemical equation likely to baffle scientists, unless they're familiar with Chill-N Nitrogen Ice Cream's periodic table of flavors. Then they'd know that the "equation" translates to vanilla ice cream, chocolate fudge, and marshmallows—resulting in a sort-of s'more sundae that should be kept far away from campfires.

Chill-N's science-class vibe is inspired by the ice cream itself, which the shop creates by flash-freezing ice-cream or yogurt with pure nitrogen. Customers start by picking either ice cream or yogurt as the base, then flavor it with natural ingredients like pure vanilla or some of the 60 pounds of Nutella that Chill-N goes through each week. They also get to blend in any of the nearly 20 mix-n's on the periodic table, including little-known elements such as gummy bears (Gb) and Pop Tarts (Pt). The shop mixes it all together, then adds a hefty blast of liquid nitrogen. Because everything is frozen so quickly, it produces ice crystals much smaller than any you'll find in mass-produced ice cream and incorporates almost no oxygen, resulting in a thick, silky mixture that the Miami New Times called "the creamiest ice cream you'll have in Miami."
