Hypercolour ice cream changes hue as you lick

A physicist has invented a way of making ice cream so that it changes hue from pale blue to deep purple to pink in response to being licked.


Hypercolour t-shirts came and went, but hypercolour ice cream might be something we could get our tongues behind. Everlasting Gobstopper this ain't: rather than layers of colour that are revealed as you lick the surface, it's the ice cream itself that changes colour.

It was invented by a team led by Spanish physicist, engineer and ice cream enthusiast Manuel Linares, whose love for the confection led him to what he described as a Masters Diploma in Creating Artisan Ice Cream at the Asociación Empresarial Nacional de Elaboradores Artesanos y Comerciantes de Helados y Horchatas.

This, in turn, led to his creation: Xamaleón, a means of treating ice-cream so that it changes colour as it is eaten. Linares was, he told Spanish website Cocinatis, inspired by British food inventor Charlie Francis' glow-in-the-dark ice cream.

"I like playing in the lab and I thought I will try to emulate the British Charlie Francis ... and even go a little further and create an ice cream that changed colour," he said.

The ice-cream -- fruit salad-flavoured and a pale blue in colour -- is sprayed with what Linares calls the Elixir of Love, an all-natural and fully edible spray, the contents of which he is unwilling to divulge at this point, as it is still patent pending. He did, however, reveal that several factors affect the change: temperature, oxidation and the acidity of the tongue.

If you want to try the ice cream, it's possible that you'll have to travel: it's only sold in Linares' IceXperience ice cream shops in the towns of Calella de Mar and Blanes in Spain -- although the inventor has said that he does have further plans for his creation. It's not all he has up his sleeve, either: he is also working on a blacklight ice cream and one that changes colour from white to pink.
