The Daily Mail: The ice cream that changes colors as you lick it: Physicist invents 'magical' fruit-flavored treat using secret recipe.

While some physicists may be working on string theory or quantum mechanics, Manuel Linares has decided to turn his attention to something else entirely – ice cream.

The Spanish physicist and now professional cook has announced that he has invented a 'magical' ice cream that changes colour as you lick it. Dubbed 'Xamaleón', the ice creams tastes like a mix of fruits and was created during a cooking course attended by Mr Linares in Barcelona.

Everyone laughed at his idea, but as a physicist he knew that there are various possibilities that might work, the 37-year-old told Cocinatis.
