The 196 Below nitrogen ice cream pop-up cart has been making the rounds of late. You may have seen it at events such as the Greek Festival, Laneway Festival and the South Melbourne Night Market, and been intrigued by the premise of nitro-ice cream (ice cream flash-frozen with liquid nitrogen).

For this Saturday's White Night, co-owners Steve Felice and Glenn Storey, who started the business a year-and-a-half ago, have created a new type of ice cream: neon. “We always try to think outside the box for each event we do,” says Felice, “For White Night we wanted to play with people’s minds.”

The ice cream has been made with a specialty food dye containing the chemical compound fluorescein (the same chemical used for blood-flow tracing in medical diagnoses), which glows under UV light. According to the supplier’s website, the food dye is certified non-toxic by the Therapeutic Goods Administration.

The flavours chosen to go neon are mango-passionfruit, pine lime and redskin. To optimise the chance to glow, the 196 Below cart will be decked out with UV black floodlights. The nitrogen ice-cream bar will also be selling regular, non-fluroscent flavours, including chocolate brownie and salted caramel as well as nitro shakes all night.

196 Below will be stationed in Alexandra Gardens throughout White Night, next to the Indie Stage.
